I don't like this logic because it implies other races don't have issues with the police.
Remember that white kid who was shot in the back by police after "refusing to comply" when he was wearing noise-cancelling headphones and walking down the street?
Or when a white guy called the police and said his schizophrenia was acting up and he needed help, only to be killed by the police while they laughed and cracked jokes about him.
I'm sure you at least remember the white guy who was killed in the hallway while police were barking contradicting orders at him on how to move down the hallway.
There is an issue with discrimination in the police department, but don't act like abuses of police are some issue that only are a problem that only black people have to deal with.
I'm not saying Black Lives Matter is a bad slogan, I just think that thing you posted is bad.
Wasn't Black Lives Matter on the ground for all of those?
