Flash bangs can kill or render a person totally deaf in such a small space. those things need to be outlawed ESPECIALLY for cops.
A cop only wants to go home, what does it matter there is a body count to accomplish it. (worst case scenario)
Reminds me of the time not so long ago when cops tossed a flash/bang through a window and it landed in a baby's crib, causing the grievous damage one would expect.
