I have a problem with both.

The shooter for obvious reasons.

BLM for a number of reasons. Many of their protests are disruptive by blocking highways. In the last few days we've seen many protesters in several cities arrested for doing that, as well as throwing things at cops.

But even more than that, the statistics simply do not support the basic contention of BLM that there's an epidemic of innocent black males being gunned down by cops. Nor that the morons with their signs and "What do we want?! When do we want it?!" nonsense would care about the facts. Much easier to not acknowledge the real problems in the black community and follow the narrative (often fed to them by white liberals) of them being victims.
