I think it would make a difference for the people who don't trust the police narrative, would go to a site to protest, and become either a standby or active participant to a riot.
I agree with what @Sohei said, in that you will always have some bad actors finding anyway to start problems. I also understand that mob mentality is a lot easier to influence the larger and more volatile the crowd is.
The idea from a LE positive standpoint is that community review councils would help to limit the influence of these bad actors by reducing the number of people in the streets.
The idea from a community activism standpoint is that it would help prevent false narratives and attempted coverup by PDs.
