at least, while they are active duty. Once you are out (which means if you did 1 tour you are past your IRR time as well), then you're out.
**** does indeed happen. the law of big numbers always comes through. if you use a non-lethal weapon on a crowd, no matter how comparatively gentle, eventually you will seriously hurt someone. and police are indeed human, and subject to all of our foils. which is why I am proud of them - given the actions of the crowd, they acted with admirable restraint.2) Police are humans just like the rest of us. They get twitchy and nervous, makes mistakes and overreact just like everyone else. It's really a high-stress job, and when you combine that stress with a volatile situation w/ demonstrators, and a lack of experience with regard to riot/crowd control tactics, **** just happens sometimes.
