Lotsa nasty shit here. Without any evidence, I am willing to believe that the cops killed the kid unjustly, believe it or not. Given the recent acceleration in the militarization of police, this is a natural side-effect. Recruit sub-70 IQ morons for their ability to "obey", and then give them weapons of war. Don't be surprised when the go to war on anything.
We reap the whirlwind.
