Much of the movement is predicated on the demonstrably false narrative that police officers wantonly and without justification murder blacks. Unfortunately, this narrative finds a receptive audience within academia because it gels with leftist beliefs that the police are racist barbarians. In my mind, the rush of academics to embrace BLM and to lend it academic legitimacy is shameful, entirely partisan, and even cowardly.
Attached below is an article by Heather MacDonald that she wrote for Hillsdale College. I attach it here because few scholars read outside of their narrow disciplinary confines. Do yourself a favor, and read what Heather has to say about BLM.
