I'm not even from the US, but these worrisome trends have been obvious for quite a while now, in many different ways. Like the mere existence of crowdsourced maps of police killing family pets [4] and something like "swatting people" actually being a thing, which is reserved in its severity pretty much to the US [5].
Note: I'm not trying to paint a super bleak picture of "all US police are evil", I just think there's a very real problem there. A problem that seems to be mostly driven by a culture of "War", like on drugs and on terror.
