When all you know how to do is fire a gun, the bodies start piling up.
I'm not for the idea that people need to be protected from the world, but people need to learn how to protect themselves from destroying the world. Both abstractly, and in the cases where cops make mistakenly **** others. I know it's a mistake, but when there are no penalties for mistaken police officers. The law protects them like they just made a small boo boo. Peoples lives hang in the balance.
