Nobody here understands why you are so unable to reform the police. The clear problem is a severe lack of police accountability, a lack of non-violent training, way too short training spans, an omnipresence of guns, a militarized police and a deep-rooting institutional racism.

Most of the world does not have a chance protesting the police. The thought of doing so will get you locked up. If you think you have it bad in the US, you have no idea how it is overseas. The police in developing countries get away with everything.

Also, here's a repost of a comment on this page from 2014, about civil wars:

Civil wars are first and foremost about local score settling. The trigger isn't some guy going door to door saying "you know those Yazidis? We're starting a group to get rid of them, would you like to know why?" Everyone was already itching to kill the Yazidis. The trigger in most civil wars is the sense that the long-repressed vengeance on your nearest and dearest enemies has become possible.

Civil wars are almost never geographic at first. Syria was not divided into "rebel" and "government" territories until after several weeks of fighting. Why? Because the government troops and the people who hated them were evenly dispersed around the country. Once the shooting broke out, some local battles went one way, some went another, and each side eventually had to work out supply lines connecting places where they'd won. Your loyalties aren't determined by your residency, your residency is determined by which army you're running away from.

Civil wars aren't anybody's program. Usually the two sides each feel like they are legitimate, and can't figure out what the other guys are playing at. They think "shit, these guys are clowns, let's just get them out of the way." Everybody underestimates the consequences of their actions, the time it will take, and the dying that will happen as a result. Nobody in Syria in 2011 was saying "right, lets call a protest, and in three years we'll be holed up in a burning hotel shooting twelve-year-olds in the head as they pull their mothers' bodies from a drainage canal!"
