If the police were taking care of the problem, then we wouldn't have a problem, and that's the problem.

I think the police need to track down the "source" of the instigation of these flash mobs. I would be willing to bet "community organizers" are at the root of this.

You can bet your ass they are. You can also safely bet the farm on that they have told the participants that they do not have to worry about the cops messing with them.
