I've been thinking about this all day at work.
Around here, one of the main hobbies is dropping rocks off overpasses. They can't catch those guys, so how would they catch a terrorist aiming at the drivers of gasoline or chlorine tankers?
Are the people who buy them (esp after China gets the mfg details) going to lock them up when not in use? NOPE! Their brain-dead kids will be on the streets aiming them at drivers, cats, dogs, birds, livestock and anything else that moves. If they insist on making these things available, anyone seeing someone using them for damaging a live creature should be legally able to knock them down, sit on them, and burn out THEIR retinas, on the spot!
It's obvious to see that America's technology has WAAAAAY exceeded it's sense of responsibility.
Oh.... sorry.... I mentioned the R-word. Politically incorrect, I know.
And it doesn't make any difference that they post "This is not a toy" fifteen hundred times on their website. It will be considered a toy and used as one.
You can buy a lot of USEFUL kit for a grand.
