Yeah, paintball guns are the latest in "Less Then Lethal" arsenal that cops have to use in riot situations.
You wanna see somehting fun?
http://www.pepperball.com That'll make your skin crawl. Or, go to the 'good stuff' :
http://pepperball.com/products/projectiles.html If you don't know it already, "Oleoresin Capsicum (OC) Powder " is the same kind of stuff they use in cans of "Pepper Spray". "Hey ref, check THAT."
Saying that this stuff is "non-lethal" is a misnomer. Many civilians are killed every year with rubber bullets, mis-used cans of mace, and so on. I inwardly cringe to think of this stuff being misused. I used to worry about kids doing drive by's with paintball guns, imagine the backlash if this is abused too.
And, FYI, I've SEEN the Airgun "Military round" in action. LEmme tell ya, I do NOT Want to get hit by that one. Nope, no thank you.
