Get your logic put of here, its racist.I don't agree with what they did, but much of the BlackLivesMatter movement is essentially just Anti-Police. They put their lives on the line daily, and to have it thrown back in their face, is quite annoying I'm sure.
There isn't much evidence either to suggest that White cops are on a rampage, killing Black people. Black people suffer from racial profiling, of course, I doubt anyone is ignoring that, but in terms of being shot dead by the police? I've not seen a single report that suggests there is an epidemic going on.
Black on Black crime is larger than White on Black crime, including the Police. But you don't see the BLM movement trying to make the situation better, you don't see them trying to reduce gang culture amongst teenagers, you don't see them trying to improve education or social programs in poor areas. What you see them doing is being racist, abusive and rude and doing nothing more than blaming the police.
