ALL lasers have a warning sticker saying not to look into the beam. People like this kid are the reason that responsible people like those on laserpointerforums.com will soon not be allowed to have lasers.
Almost all of the websites that sell high powered lasers have a long warning on the website. Dealextreme.com will not even ship a laser >5mW into the Unites States.
I also can't believe that this kids parents did not know about this. 150mW lasers aren't an easy thing to find in a local store. If this kids parents allowed him to order one of these online then something is wrong there.
Go to wickedlasers.com and look at the safety warning for the Arctic. If you did what this kid did with that while not wearing googles, then you have it coming.
Go to dealextreme.com, a site that would be extremely attractive for a 15 year old because of it's good prices and try to order a 150mW laser in the U.S.
Type "paypal lasers" into Google. High powered lasers are quite hard to order in the U.S.
The fact that this kids parents were unaware of him owning the laser is not "lack of government control" as you called it, rather lack of parental control.
