Would the 4 days of rioting in Anaheim about half a year ago count? Sparked by police shooting and killing 6 people in a rather short period of time that most people didn't think deserved to be shot.
Yeah the Anaheim rioting is a much better example. And while I'm not sure any of the officers involved ever faced any punishment, that might have had some positive effects. It's too early to say but the Anaheim PD surely got some kind of message. It's a good start, but its still not enough to say "Ok, time to give up, let's resort to violence."
This incident will cause people to look at the LAPD and other departments with more scrutinty, which will hopefully bring about change and reform because of social outcry. All this guy really has to do is to stay hidden and keep this in the public eye and the police maybe reformed all on its own.
Or people will dismiss everything he said because he clearly went crazy and was maybe always crazy and the LAPD will become paranoid because they feel obviously targeted. If anything's going to put scrutiny on the LAPD its shit like opening fire on vehicles because they looked like the suspect's and not really anything Dorner himself did.
