You have to identify the problem before you can find solutions. And simply saying the police are out to get all young black males doesn’t do it.
And also differentiates between the concept that Black lives matter (of course!), and the organisation Black Lives Matter, which has some pretty dubious aims. See its website. Amongst other aims, they want to (1) destroy capitalism (2) destroy the nuclear family and (3) abolish the police. As Zuby notes: these are “bad policies” that will most affect minority communities.
