What, did you think you had rights? Well you don’t.
As attorney Scott Greenfield explains here, there are so many layers of judge-made exceptions in the U.S.A. at this point, they amount to an almost-blanket license for cops to kill whomever they feel like and get away with it virtually every time. Everything they do is reasonable, you see. And if you don’t, that’s okay too, because you just have to trust what the very professional government employee says was his perspective at the time: he was in danger maybe. Good enough.
