Whether a tree falls to the south or to the north, in the place where it falls, there will it lie

I cannot get my head around this. To me this is abuse of an individual by an officer. I see no reason for the level of violence used on these people, and I am so glad I am not at any of these events because just watching the video I can feel my blood boiling and my body heat rising. I won’t share the thoughts I have towards what I would want to do to those officers, but I’m sure you get the idea.

Now, I don’t agree with the tactics of these protesters and how they are going about promoting their message, but despite that, where is the line drawn to what is appropriate when treating someone?

Is my anger misplaced or misguided?
