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?
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".
No folly is more costly than the folly of intolerant idealism. - Winston Churchill
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.........
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.
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.
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.

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.
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.

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?

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?
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.

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.....
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.
Sure.
Of course, you can get lasers in at least three colors, probably more. And it's significantly hard to filter out just one wavelength, without filtering neghboring wavelengths as well. Which would mean in this case they would want to filter out green. The color of treetops, and grass, and overall a significant portion of the Earth's surface.
And of course, following that logic, you'd want to filter out the other main colors that lasers come in. Red are extremely common, and blue are just starting to get on the market. So we'll filter both of those out.
You know what would be a good filter at this point? Polished steel. It'd reflect that laser right away, and convently blocks all the colors mentioned.
'Sensible' is a curse word.
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.

Actually, in the real world you should take the helo's tail number and complain to the FAA. The FAA does go after aircraft that fly too low, community noise complaints are something they take seriously - and that includes bumping heads with local police departments.

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.
Good security is based upon reality and common sense. Common sense is a function of having common knowledge.
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.........
I am a laser engineer at work (trained to work with dangerous high power class IV lasers) and can tell you that there are limitations to this approach.
The filter material at most laser wavelengths would not be clear. My laser safety goggles for 532nm green lasers are dark amber, 660nm red laser goggles are blue. Not practical for navigating aircraft around obstacles.
There is no single filter that is effective for all wavelengths of lasers (green, red, co2, etc).
Also the optical density for a single filter - the blocking capability of the filter - is not the same level across different wavelengths. And optical laser filters do not block the laser beam, they reduce the energy level. Prolonged exposure even with laser safety goggles will still cause eye injury; the object of the goggles is to reduce the energy long enough to account for the reflex time of turning your eyes away from a laser beam and thus avoiding eye injury. This does little good in a cockpit when someone maliciously aims a laser beam at an aircraft.
There is also the hazard of refracted and reflected beam energy. The beam will be refracted as it strikes the cockpit glass and its energy may or may not be attenuated, and there is also the hazard of beam reflections off of objects in the cockpit. The danger of stray beams in this condition is very real and it may be near impossible - while affixed to the pilot seat via seat belt - to avoid exposure to any laser beam. There is also the remote possibility of the refraction of the glass having a focusing effect on the laser beam and exposing the pilot to higher w/cm^2 laser energy at the wrong place.
I have never experienced a laser eye injury, but have been told in laser safety training that they are extremely painful.

*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.

The Supremes issued a 5-4 ruling back in 2005 that sentencing guidelines are not mandatory, they are advisory only. IANAL either, but here's a link from the National Association of Criminal Defense Lawyers:
http://www.nacdl.org/public.nsf/mediasources/20050113b
And just this month a 7-2 ruling in the Minbrough and Gall cases, related to crack cocaine sentencing guidelines, again they are advisory only, not mandatory. Here's a link from the LA Times:

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.
Eternity: will that be smoking, or non-smoking? I Corinthians 6:9-10
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.
