Regardless of how moral the goals are of the group. The reality is that BLM is a decentralized group that has actors which freely associate and disassociate fluidly. Because of this, it would be reasonable to assume that this is part of BLM as the overall group are not outing these individuals and are in fact concealing their identities.

Unfortunately, the lack of self policing with the group has lead to this result.

If it were the latter, than I would have expected more people associated with BLM to disown/disavow the violent criminals, rather than making excuses for their behavior.

BLM as a whole was done by independent actors, so what is the distinction?
