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."
"Don't lase me, bro!"

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.
Give me Classic Slashdot or give me death!
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...
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.

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.
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.
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.
