How many times does it have to be said? Lasers don't kill people, sharks with frickin' laser beams attached to their heads kill people. That doesn't make the laser evil.
Wait, did someone argue that a laser is inherently evil? Yep. Might it have been the United States government? Yep.
Of course, the government has lots of lasers itself, and is desperately trying to make some that can actually be used to kill people and melt things. (You may be remembering those laser-equipped 747s that were supposed to shoot down missiles. Didn't work, we learned $5.3 billion later. But they'll get it right this time.) So it may seem odd that it would argue in court that lasers are "insidious instruments normally used for criminal purposes," and that possessing them is "indicative of a readiness to do evil." Why would it say that?
Because an immigrant had one.
