I disagree. There have been some organizations that have done that on a small scale, but nothing as large as the anti-Trump protest. Plus consider that most of the anti-Trump protesters and BLM protesters are young people. Take that along with the publicity they receive, and apply it consistently you would get some results. The attitude that gangs are only going to stop themselves sounds like giving up and admitting defeat. There has to be a coordinated effort between politicians, the police, schools, churches and social organizations. In fact, because BLM is so social media savvy, it is in a better position to do more and to take a leadership role. I'd even suggest a deputized, concealed carry, vigilance group comprised of law-abiding people from the community to monitor and assist with law enforcement. They could be the first responders. Even some gangs might be willing to help. In the 1970s some Chicago gangs turned from violence to helping the community, but they didn't get political support and returned to their old ways. But there has to be a community decision that says that violence and general criminal behavior is no longer acceptable.
