Slashdot Mirror
Couple Busted For Shining Laser At Helicopter
coondoggie sends us to another Network World piece, this one about a couple charged with shining a green laser into the cockpit of a police helicopter. The FBI and the US attorney's office charged the California couple under a federal statute. They could end up paying a $250,000 fine and doing 20 years of jail time. "The complaint states that on November 8, 2007, at about 10:55 p.m., a green laser beam illuminated the cockpit of a Kern County Sheriff's Department helicopter, which was flying at 500 feet during routine patrol in Bakersfield, California. When the light hit the cockpit, it disoriented the Kern County Sheriff's pilot, causing pain and discomfort in his eyes for a couple of hours, the FBI said in a statement."

Was the laser attached to a missile launcher?
or a shark?
Sums it all up, I think.
Put one of these powerful green lasers in the hands of an idiot and see that the first thing they'll do is shine it on somebody's face.
I hate the police as much as anyone, but that's not cool. Unless the helicopter is spotting pot farms, in which case an anti-aircraft missile should be used instead.

It was a GREEN laser, which puts out a lot more power than your standard red keychain ornament. One of the advertised uses for a green laser is as a "sky pointer".

in the eyes, and over 500 ft?
The article didn't seem to indicate what kind of laser they used.
I also wonder how bad they where effected if they where still able to find the laser. That is just a point of curiosity. Certainly shining a laser of any significant power at an aircraft is to be frowned upon. Obviously excluding vehicles of war.
The Kruger Dunning explains most post on
Are these common laser pointers you find for use on PPT presentations and exercising your cat/dog without moving from the sofa? Or are these more powerful items?
My guess is that it was something like this, but it could have been something more powerful like this. Both are consumer devices, but both are still potentially damaging with sustained exposure.
If it was a consumer device I have a hard time buying it "causing pain and discomfort in his eyes for a couple of hours" so maybe I'm wrong. That or the FBI is exaggerating just a bit.

Good. The maximum punishment seems a tad harsh, but yeah, they should, in fact, be busted. What they did was dangerous, and they actually hurt somebody (the pilot). It could have been worse. The pilot could have been blinded. He could have crashed the helicopter right into somebody's house. Okay, so maybe they didn't mean any actual harm, and maybe the judge will take that into account.
These are generalisations but :
Presentation pointers are red, very low powered, you can't see the beam without some kind of mist, you can get them for under five pounds in the UK all over the place, normally smaller than a pen, but thicker.
Green lasers are more powerful, you can see the beam in clear conditions, they cost an awful lot more ( somewhere between 100 - 200), are much larger, closer to say, a couple of coke cans stood on end, and can cut through a polystyrene cup....
Or at least that was the case the last time I looked maybe a year ago, I just took the first google hit that caught my eye and unsurprisingly they've got smaller and cheaper now : http://www.thinkgeek.com/gadgets/lights/5a47/
heh, the thinkgeek page even specifically points out "Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely."
So, what if these people were using it 'as advertised', to point to sky objects, and this pilot flew INTO their beam? Is that still a chargeable crime? Do they have to prove intent of these people trying to shine it at the helicopter to cause damage or pain to the pilot?
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
Just because a person did not intent to do harm when harm occurred, should not protection from some form of punishment. This couple was operating a possibly dangerous device in a definitely unsafe manner. Should they get 20 years and a $250,000 fine? No. Let's reserve that for the people who had intent to harm. IMHO, they should just be fined and the lasers taken away. Our jails are already full all over the country.

I googled around and found this article comparing red vs green lasers.
From the article
Red versus Green laser pointers
The most obvious difference between green and red laser pointers is beam visibility. The human eye is most sensitive to light with a wavelength of approximately 555nm (yellow/green) which makes green lasers much more visible than red lasers. Green laser can appear to be roughly 50 times brighter than red lasers.

Part of the problem is that Laws have become so stict that it prevents exersizing justice. Is the action illegal... Yes does it deserve 20 years and 5 years of pay, no. What would be more fare would be $5,000 fine. for a first offence. These huge life killing fines are unjust for the crime that are caused forcing the person into jail (for people who are not a continued danger to society) or Paying huge sumes of money will only make the problem worse... Oh a person commited a Crime Put him in Jail for 1/3 of his life and make sure when he gets out he can't pay any bills... That'll make sure he won't comment a crime again... a $5000 fine will be enough for the person to feel it and not willing to try again, but yet will be able to live his life as a productive and law abiding citizen.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Higher watt green lasers like this ClassIIIB http://www.thinkgeek.com/gadgets/lights/ can definitely be considered a hazard in the hands of idiots.
Alright, let's see here. An average divergence for a class 3B green laser is around 1.2mRad, with a (on the large side) 1.5mm aperture.
.6 ft diameter which, while probably larger than the distance between eyes, I'd have
At 500 feet (152.4m):
1.5 + (152.4 * 1.2) mm = 18.438cm
Roughly
to say people that aim at planes and helicopters have really good aim. While the heli pilot could
easily have been hurt if this laser was of the higher powers one can easily get around the web
(ie 200mw), a plane is much further up, the cockpit would merely be green, the pilot would not
be hurt. Remember that energy decreases with area. It's probably a distance squared type thing, but
my physics is rusty.
Is it really that hard to NOT shine a laser at a helicopter? I mean the thing takes up maybe 30'' of arc of 180deg of sky... Idiots.
What right do you have to create a dangerous situation for pilots? The fact that no accident happened here should mitigate the penalties, but would you really want to be on the receiving end of a laser beam when you're trying to fly a helo or plane?
Put one of these powerful helicopters in the hands of a power-hungery cop and see that the first thing they'll do is noisily hover over my house, disrupting whatever I was doing.
Seriously, do they not realize that they're *also* a nuisance to people on the ground?
Apology to Ubuntu forum.
Can't they develop cockpit glass that will filter out that particular wavelength?
but more then if the accidentally shot someone with a gun?

The Kruger Dunning explains most post on
FWIW... I have a friend who was lasered (is that a word?) during one of his cargo flights. With beam dispersion as it is on consumer-grade devices, you get quite a wide beam at 500+ feet. He described it as the entire cockpit turning green, so he closed his eyes. It would have been fairly easy to look out the window and radio the authorities with the approximate location, but he chose not to. With a powerful enough laser, it could definitely do damage to someones eyes, if not at least cause disorientation - something you definitely don't want when you're flying an aircraft.
In theory, theory always works in practice. In practice, theory rarely works. <><
We can probably agree that at first glance, the FBI going after this couple because the pilot of the helicopter had a headache for several hours seems like using a jackhammer to swat a fly. But consider: lasing an aircraft (putting a laser on an aircraft) for any reason is a federal offense, making it the FBI's domain. [FYI the reason it is a federal offense to begin with is that the air space over the country is not considered "state property", otherwise you could have a California Aviation Administration, a Nevada Aviation administration, etc. etc. and all of the aviation systems need to work together]. Coupled with the fact that virtually everything you can do with an aircraft can have an interstate commerce connection, making it Federal vs. state anyway)
Anyway, this has to be considered a significant offense for two reasons reasons, the first being the one they quote: disorient a pilot and you put the pilot and any one in the neighborhood of the craft in danger. Think of the response if you dropped a paint filled balloon from an overpass onto a vehicle on a busy freeway, same type of thing. The second reason is similar: because lasers are damn straight sighting mechanisms and reflect back to an observer in an electronically or optically observable manner, anything from a high powered rifle to an anti-aircraft gun or missile can be targeted on the aircraft resulting in a significantly higher probability of a hit.
What the law can't do is say "well, there's no harm to doing ___X___" if every time someone does ___X___, other people are put at risk. Which is why "driving under the influence" is a crime even if no one got hurt. Maybe the couple doesn't deserve a huge fine and twenty years in jail. But they did the crime even inadvertently and there has to be a measurable penalty as a deterrent to other idiots doing the same thing.
My question is, are we readers on slashdot so reactive to anything the government does that we tacitly give permission and headline space to all of the idiots of the world who get in trouble for doing what they ought to have known they shouldn't?
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
From the article, they claim, "...Snow told investigating agents that she and Dooley were standing in the driveway on November 8 and "taking turns shining the laser around watching the tracers in the sky.""
If they are telling the truth, then this was a horrible accident. If they are telling a lie to protect themselves from harsher punishment, then harsher punishment they should get. Unless a third person can come forward and state that harmful intent was desired, then the judge will have to go on the sworn testimony of the two.

How does a green laser make itself visible where a red laser would not? Does a more intense beam require less "stuff" in the air to create reflections and thus a visible beam effect?

I'm glad these guys were arrested and I hope they get the book thrown at them.
I was driving along the highway one time at night 2 years ago, and a laser beam was shined into my car. For all you guys that think that the pilot is bullshitting, you guys are idiots. The laser flashed me for a split-second, and even though the laser went through the car windshield or whatever (I'm not sure where it came from) I was totally blinded. I was able to safely pull over, but had I been driving fast or in the middle of traffic, I probably could have easily killed my wife and my two kids. One eye was worse than the other but it got better, but as a precaution, my wife drove the rest of the way, but I was infuriated that this happened, and that some dumbass with a laser pointer could have killed me.
We need laws like that so people who attempt to blind people piloting planes, helicopters, cars, or whatever go to jail and learn a good lesson.
...or a shark launcher?
=Smidge=
Even shooting a laser through a public space (meaning anywhere outdoors) in the US is considered a misdemeanor. Pointing at a police office is a more serious crime because they may mistake it for a gun.
So while 'sky pointing' is advertised as a feature, it doesn't actually mean that it may be used that way.
I just purchased a 55mw green laser a couple months ago, and I love it. It goes for miles with a clear, visible beam at night. It can even pop black balloons at close range! I take care to look for low flying aircraft before I point it into the sky, and I always make sure that it's not being aimed at anyone. Time-lapse laser photography is very good fun, too. I really wish idiots like these two wouldn't ruin it for the rest of us.
That's the problem. Green lasers are powerful, and they are very bright (intrinsically, plus the sensitivity of our eyes to green). If you misuse them, you can hurt somebody with them. What else is new?
I own one myself, and use it as a pointer for astronomy. It works really well. I am careful where I point it. I am careful who I allow to use it.
If I deliberately pointed it at an aircraft to try to distract the pilot, that would indeed be A Bad Thing.
If an aircraft accidently happened to wander in to the path when I was showing somebody where M31 or Comet 17P/Holmes was, is it a crime? I don't think so.

Only Duke Nukem knows for sure!
I can't remember the website off the top of my head, but a few months back, I ordered a green laser pointer for about 20 bucks. It was the least powerful of the green lasers they had (5mW), it can't cut through anything. It's a normal pen size, similar to the one you linked on think geek. They had increasingly powerful ones, but the price differences were very small.
I use mine primarily to point things out while documenting buildings, and went with the weakest green laser just for a little bit more safety. It's still significantly brighter than any red laser pointer I've ever seen, plus human eyes are much more sensitive to green light than red, so it's really easy to see. I can see the beam itself at night, but not during the day. If I have just put fresh batteries in it, and shine it at a white projection screen, the spot is bright enough that it's unpleasant to look at.
One time I threw a brick at a duck.
I was a laser and electro-optics major in 1982 and back then it was explained to us that pointing a laser at any aircraft was a felony. Of course, the lasers we had back then were considerably less portable (and we had to carry them uphill, both ways, to classes), but my point it that this law has been on the books for a long time.
If an aircraft accidently happened to wander in to the path when I was showing somebody where M31 or Comet 17P/Holmes was, is it a crime? I don't think so.
It may not be a crime, but you may still be liable for the incident. It is probably your responsibility to not illuminate aircraft. Much like it is a shooter's responsibility to make sure downrange is clear. You may set up a target in the desert and intend to shoot only at the target, but if you hit someone/something a mile downrange you are responsible.
It is a virtual certainty that if a crash results you will be sued into oblivion.
Aircraft don't suddenly appear, they move across fairly predictable paths.
If an aircraft were moving towards the area you were shining the laser, would you turn it off, or keep it shining?

Where "use wisely" probably means if you're going to point these things at helicopters, to do so from somewhere they cannot identify who you are.
Nobody was accidentally killed in this case but it could have been close. For example, compare RIAA fines against murder charges and you begin to realize it's not a level playing field

If an aircraft accidently happened to wander in to the path
If it was a plane it'd be flying at anywhere from 100 feet/second on up, so beam exposure would be sub-millisecond on any given part of the plane (or cockpit). Since helicopters can fly slowly or hover, it's less certain how long an accidental exposure might be -- although presumably the whole point of a green laser is that's it's bright enough to see the beam reflecting off dust in the air. The pilot might be a little surprised to see a beam materialize in front of him and move suddenly to avoid, but that's not the same as having the thing illuminating his cockpit. The latter seems to imply some deliberate aiming on the part of whoever is shining the laser.
-- Alastair
if the "perpetrator" managed to cause pain and discomfort by pointing a laser in the eye of a person flying a helicopter (fast moving target) at the altitude of 500 feet (make 900 for an oblique "hit"), and trough a thick (plexi)glass window, then that guy should be hired by the special forces as a super-sniper, and get a place in the Guinness Book too.
No no no. It completely depends on the statute. There are plenty of laws that only require knowledge and there are even strict liability laws that do not require any knowledge of the illegal activity taking place. Violating them can land you in jail. Gross negligence can also land you in jail.
Right, because the citizens of Bakersfield, California are powerless to regulate Police Department policy... oh, wait.
See, these people would have a lot more of my sympathy if they had first advocated a change in Police Department policy, and then when the majority of their fellow community members declined to support their cause they moved out of that community to a community that agreed with their preferences, and the Bakersfield PD helicopter followed them to that new community and continued to harass them.
Police Departments don't magically appear out of nowhere, like some mist-born horror that must be battled at all costs with whatever weapons come readily to hand. They are, by and large, the product of communal agreement, and most communities--including Bakersfield, California--have plenty of resources for community members to debate their preferences and reach a peaceful consensus on policies that affect the community. If this couple were living in the mountains of Afghanistan in the mid-1980s, I could understand them attacking helicopters with lasers and more. But in Bakersfield, California? Their beef is with their fellow community members who set the Police helicopter patrol policy, not the pilot of a helicopter in flight.
Any sufficiently well-organized community is indistinguishable from Government.
You got it backwards, except for lightsabers. X-wings, Y-wings, A-wings, and Corellian Corvettes have red lasers. TIEs and Star Destroyers have green lasers, as did the Death Star.
I see your informative link, and raise you a pithy comment.
I believe that the reason you can see a green laser beam is because that wavelength of light is not readily absorbed by water molecules in the air, thus some fraction of the beam is reflected. In the case of a red laser, water molecules readily absorb red and infrared light (case in point - if you go scuba diving greater than ~30 ft down, and cut yourself, you bleed green - all the red light from the sun is absorbed by that depth) and thus the beam is less visible.
The secret to creativity is knowing how to hide your sources. - Albert Einstein
Those lasers are powerful enough to show up (ie: a green line) when pointing out stars and constellations to your significant other or children.
I'm not really sure how a laser would bring down a plane though. Do you really think the pilots are up there doing dives and loops and such?
am I reading slashdot? or Rush Limbaugh's Discussion Board for the Advancement of Police States? If they were maliciously trying to tag the pilot w/ the laser, then sure, punish them. But if they're playing with a laser and it happened to flash across the pilot's face...I dunno--it seems extreme to me to freak out and invoke the FBI. Accidents happen--this wasn't nearly a big enough deal to be worth the fuss, let alone condemning the ruthless RadioShack Laser User Terrorists.
Misdemeanor? Are you sure about that?
They're a popular accessory for stargazers, as seen here. Obviously, shining them at people/aircraft is a bad thing, but I didn't think their proper use was illegal.
Who else is hoping someone got a picture of these two being arrested so that they can add it to the ThinkGeek product page as an action shot?
I am Jack's complete lack of surprise.
Well for the laser to shine into the cockpit and hit the pilot in the eye then it couldn't have been directly above them. The article says the helicopter was at 500 feet -- it would have been impossible to miss if that was anywhere near them. So it was likely quite some distance away, and over a city, so it's not an unreasonable supposition that they could neither hear nor see the helicopter.
:(
However also according to the article, one of the couple said that they had been "taking turns shining the laser around watching the tracers in the sky."
Waving a green laser around at a relatively low angle at the horizon in a populated area just for kicks seems pretty irresponsible. If you want to do that just point it at the ground nearby where you know it's safe (and makes neat patterns on the grass =D). This is a far cry from pointing at the night's sky to point out stellar objects, especially since normally astronomy is done away from a city where the lights of a police helicopter would be obvious, and you aren't waving the laser around so the odds of someone moving -into- the beam are pretty minimal (as opposed to here, where they were sweeping large swaths of sky).
I'm not sure this should be a criminal offense in this instance, but a pilot was injured and could have been blinded, and people do need to learn how to use lasers responsibly before the gov. decides to take them away from us.

"A great democracy must be progressive or it will soon cease to be a great democracy." --Theodore Roosevelt
I agree and I call shenanigans on the cops. Try and point a laser pointer at a stationary object that far away. You can't hold it still enough. Even if a helicopter was hovering in place, I'll bet that the victim pilot couldn't hold a beam on something as small as a helmet visor inside a cockpit from a quarter-mile away for anything longer than a fraction of a second. Wahhhhhhhh.....
Sorry, not buying it. The odds of shining a narrow focus beam directly into a pilot's tiny pupils, over a great distance, likely through a floor/door/visor, etc. are just too incredible.
I've got choppers flying around me here and I just can't see it happening. Literally. Who the hell has such good eyesight they can aim a laser that well without something like a telescope, binoculars or a viewfinder? The article doesn't say but if these aids weren't present then I'm simply not believing it.
I know about morons shining these things at planes on final approach but those are people standing directly in the path of planes with the noses down just well enough to provide direct line of sight AND the pilots are looking in their general direction at the landing lights, so it's a bit more plausible - but still hard to believe.
Have you ever been blinded by a driver who didn't dim his headlights? Now imagine something about 5 times as bright. And pointed at the underside of your car.
It was a GREEN laser, which puts out a lot more power than your standard red keychain ornament.
No, no, and... No!
A IIIa (now called 3R for the type of devices under consideration here) puts out less than 5mW. 5mW of green laser light doesn't magically contain more energy than 5mw of red laser light.
Humans perceive green light as much, much brighter because we have a higher sensitivity to it. But in terms of total power, 5mW equals 5mW equals 5mW.
That said, IIIB/3R can cause temporary eye damage, though it takes some effort to target it just in the right spot and for long enough (a quick random sweep across the eyes won't do it). But "disorientation" and "hours of discomfort", over 500ft away and through a window? No. Evil piggies just want to cry victim.

If the charge is based on conduct that is defined as criminally careless, reckless as a matter of law then your "intent" isn't going to matter very much:
"I'm sorry we pointed a laser at the cockpt. I am sorry we held it there long enough to blind the pilot. I am sorry he crashed the plane. I am sorry about the people who died on the ground."
Sometimes feeling sorry isn't good enough,
Um. . . no.
A 200mw green laser is no more / less powerful than it's red / blue / infrared counterparts
of the same power level. If the couple were truly evil, they would have used an infrared
lab laser with an output of 5-15 Watts. The officer wouldn't even know what happened until
his eyes 'popped'. Infrared is actually more dangerous because of the lack of the blink
factor. Shine a bright light in your eyes and you'll close them / turn away to deal with
it. Infrared you won't even realize you're in danger until it's too late.
A green laser appears to be more powerful because the human eye can see that wavelength a
lot better than we do with the red end of the spectrum. So while it LOOKS brighter,
200mw is still 200mw any way you slice it, thus the green lasers are no more powerful than
any others. ( Based solely on color / wavelength )

I've owned one of these lasers for a little over two years now. It is nothing short of amazing to hold in your hand and press the button on what is nothing more than a pen sized laser pointer that will illuminate an object over 40 miles away. When you first take hold of one of these at night, the desire to point out any and every object you can see with your naked eye is overwhelming. It takes a better man than I am to resist that temptation. Then if you have the opportunity to illuminate a moving object? It is a very natural desire, I've felt it. Its like seeing a car accident and avoiding the temptation to even look. It is easy to criticize.
When my wife took hold of the laser, we were driving in the car in SoCal and she illuminated a mansion up on a hill and exclaimed "This thing is AWESOME!" which was one of the only times in memory she has shown avid approval of any of my "toys". Then she said "I can see why people want to shine this at flying objects."
If you illuminate any of the reflective street signs with the laser, it is amazingly impressive. The entire sign, regardless of size, illuminates so blindingly bright that you cannot look at it. Do this at a street sign over a freeway and you could easily cause an accident.
To avoid the temptation not to play with one of these is too great. I sympathize with this couple completely.

Yes... I fly with them occasionally, and they are very aware of this. We had a call for something serious in a neighborhood next to an outdoor festival -- they purposefully kept away from the festival so that it wouldn't disturb it and wouldn't look like they were monitoring it. I know all the cops who fly in our city (it's just a handful), and they're all very professional. Hope the same's true in your city -- flying the helicopter is a privilege; they don't just stick any bozo in it.

I mean, if you light up an aircraft 500-1000ft up in the air, and you turn off the light and walk/run out of the area, how the hell are they going to find and PROVE it was you that did this??
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
actually just the opposite. You can see the beam because it is absorbed more than the red one ... and then retransmitted, which has the effect of scattering the beam.
The sun shines white, that's true. It appears yellow because the blue is scattered. By contrast the entire remainder of the sky appears blue (because the blue rays, while coming from the sun, have been scattered by absorption and re-transmission).
What an electron absorbs in energy, it will retransmit some time later.
It looks like it's just a local law here in New York City so I guess it's not everywhere. Sorry, my mistake.
As a helicopter pilot and an aviation safety officer (probably one of the few on /.) I can tell you that the danger to the pilots and the aircraft cannot be overstated. Laser illumination from the ground can result in full or partial blindness, and it can be either temporary or permanent. If you get blinded while you're flying a helicopter, you and everybody on the bird are gonna die. No ifs, ands, or buts about it--you will be a smoking hole in a field somewhere, and if you come down in civilization you'll take folks on the ground with you. I'm sorry these folks didn't know about the law, but "ignorance of the law is no excuse" and I sincerely believe this to be a completely justified law.
Actually, there are a lot of green lasers out there that are exceeding the 5mW limit. They are not at all hard to get. You can get red ones, too, but the greenies are far more popular.
Even the "legal" ones can be easily modified by eliminating the IR filter. They put out considerably more power that way, but the IR diverges so quickly it's really only a hazard for those nearby.
My greenie cuts thin plastic, pops balloons, and ruins digital cameras. Fun stuff.
*sigh* Try RTFAing for a change... the helicopter pilot and observer traced the visible-light beam (by the backscatter) back to the house of the defendants. A subsequent search (with warrant) found the green laser pointer. The couple then admitted that they were using it on the night in question.
About the only question left for the court is did the couple shine it at the helicopter directly (in which case it was an intentional attack), or were they shining it in the sky and were just careless.
Yeah, if you used it in an open area, the cops might have more problems. OTH, it was a police helicopter, which are used to chase down suspects all the time.

We had this guy on our ship. A real "shipwreck" if there ever was one. He got the idea to paint the officer of the deck on the ship next to us with his laser pointer. Said officer of the deck was wearing his summer whites, and this brilliant red dot blooms on his chest. It was amazing! The OOD dropped to the deck, drew his side arm and began shouting "SNIPER ON THE PIER! SNIPER ON THE PIER!" Their ship went to security alert, the security teams were deployed and began fanning out on the ship and the pier, and then OUR ship went to security alert. By the time it all got sorted out, Seaman Shipwreck had been hauled off to the brig and later had himself the Big Chicken Dinner (Bad Conduct Discharge). So yeah, firing lasers at official vehicles, ships or planes is a good way to earn yourself a Darwin Award, either by measure of return fire or being put in prison long enough for it to no longer matter.

What you are neglecting is the retina absorption of laser radiation, which varies with wavelength. The human eye absorbs the most light energy in the 500-700nm wavelength range, which happens to be where green (532nm) and red (660nm) fall within. In the same amount of time, 5mW of 532nm laser energy will do more eye damage than 5mW of ultraviolet 400nm laser energy.
Incorrect. Any laser higher than class 1M can cause permanent eye damage. Laser eye injuries are extremely painful even at class II 1mW or lower levels. Class IIIR (formerly IIIa) lasers can produce no more than 5mW, but class IIIB lasers can produce as much as 500mW and can cause skin damage.
Lasers are not a controlled substance. One could purchase a class IIIB green laser that puts out 500mW of laser energy and really do damage to a pilot from the ground. If you think these people are exaggerating about their suffering, you are dead wrong.

Absolutely positively not true. Laser sources that emit a non-visible beam fall in class IIIR, class IIIB or class IV which are the worst eye hazards regardless of power. ANSI Z136.1 specifies that non-visible class IIIR or higher laser beams must be enclosed to prevent laser radiation exposure to non-trained personnel.
I work around exposed class IV CO2 10600nm laser beams capable of putting out 100 watts (that's watts, not mW) of power. The beam is invisible to the human eye yet it is capable of cutting metal. "Not dangerous at all" is a serious understatement.

That's the thing... punishments no longer fit the crime. Everything is being criminalized, and punishments far outstrip the crime or any consequence thereof. Soon enough, the government will be able to arrest you for anything and lock you away forever, or seize your assets with no obligation to prove you did anything wrong, or even present the charges against you.
Shining a green laser at a helicopter is stupid, but so is being sentenced to twenty years prison for doing it. Vote Libertarian.
Other than this text, there is no discernible information contained in this sig.
I'll order an array of those for my dark, gothic castle tower, then. Shine it over the villagers! They'll never know why it hurts so much to glance at my evil castle, they'll just know that overly curious people are punished with an unnatural blindness. Serves them right!
I lost my sig.
Pain I'm skeptical of too, and I bow to your superior experience in this regard, but even temporarily dazzling a pilot over a city is serious.
Having had afterimages for several minutes after being exposed to a specular reflection of a 5mW green laser in office-lit conditions (reflected from a whiteboard), I can sympathize.
It doesn't say the power of the beam - you can quite easily pick up green laser pointers on eBay that are advertised as 100mW or more (here in the UK, at least). Also, the copter is likely to be quite low, and you'd only want to try this at night so you could see the dot. The pilot's pupils would be dilated due to the darkness, so I can imagine quite a severe dazzling effect.
