Is it exaggeration though? When there's so many reports of clearly unarmed and co-operative black people being shot? Look at Philando Castle. Mentioned he had a legally owned gun in order to give the officer info, gets shot 7 times for it because the cop automatically went to "this black guy is going to pull a gun on me".
Or Stephon Clark, shot to death in his grandparents back yard....six of the eight hits were to his back, the other TWELVE missed. Twenty shots total. All because the guy was holding his phone.
Police overreaction leading to the deaths of people of colour is disturbingly common. So many high profile examples, most officers escaping any punishment, all for imagined slights and irrational fear. Police aggression toward poc is a HUGE issue, so calling them on an innocent person for the heinous crime of being asleep, yeah, it's flipping a coin on whether or not the victim of the malicious call gets out of it unscathed. Even if they don't get shot, people have been choked to death and suffocated by cops in the act of arresting them. Shit is scary as hell.
I'm not talking about the risk involved, I'm talking about intent. The person calling the cops didn't intend to get the black student killed. There is zero evidence that that possibility ever entered her mind.
I'm also not sure that the Yale Campus Police have much history of police brutality. Yeah, NYPD and LAPD and small town squads are full of scumbags, but campus cops? I'm really surprised they even have guns.
