Actually the 2000 police officers there had things quite under control. The media really tried their best to blow what little happened out of proportion. The police did a great job I was watching them from my 3rd story cubicle while I was working today.
The problem is that they are not afraid to behave this way. They are confident that they will not have to endure any “excessive use of force,” just barely enough to get them out of the way. So they have little to lose, and it’s just playing for them, and they will be back every time.
We would be in a much more civilized society if these people could expect to have the crap beaten out of them or worse. It wouldn’t take too many examples, and almost all of them would learn to express their views peacefully or not at all.
