There are plenty of shitty cops, and there are plenty of things that these shitty cops have done to warrant the scrutiny (ie: the idiot cop who shot Terence Crutcher in Tulsa who "didnt realize what she was doing", or almost all of the Chicago PD, or that shit with Dejuan Yourse posted last page (guy on his own porch),
the trigger happy cop who was looking for a reason to shoot a PI and the rest of the team who were trying to fabricate charges on him ), and then there are situations where people are doing the stupidest fucking things possible and the media and SJW are still going "but why did the cops shoot".
Mentally challenged man literally assumed a firing position towards the police with a black object in his hand..."but why did the cops shoot"
Dude charges at cops with a knife..."but why did the cops shoot"
Dude acts defiant at a cop who wants to ask questions, then puts his hand in his waistband..."but why did the cops shoot".
Scrutinize the shit out of the shitty cops, but dont make it a fucking witch hunt to the point where the good cops are afraid of the backlash they will receive for touching their gun.
