> So when people get upset with police for their brutality, it's easy to understand why they are outraged - it is simply impossible to do their job without violence.

I think you need to distinguish between force and violence. I expect the police to occasionally need to use force to do their job, but I never want them to use violence. What we have been seeing during the past few days is totally out-of-control violence conducted by the police on non-violent people.
