BLM is a major part of Obama’s “legacy”. He passed his hatred of Caucasians on to the uneducated, low I.Q. humanoids living among us.
I'm sure that Obama takes great pride in bringing back race riots of a scope not seen since the late 60's or early 70's. Nothing quite emboldens street thugs as having their views legitimated on national television by the Chief Executive. They knew that with Obama, Eric Holder, and Valerie Jarrett on their side, they could get away with almost anything.
Things won't go quite so smoothly for them with Trump and Jeff Sessions in charge of things.
