You know all that tyranny you hate from the right wing dick heads in this country? That’s why. And yes all forms of things have been used to kill humans throughout history, get over it. You hate the police but want to give them control of force, your naive children. You also don’t give two shits when it’s black on black crime in inner cities with handguns and drug/gang violence… you’re only worried when you see something like this on the news. Stop acting like you give a shit.
