As always, you have to ask, compared to what ? Are the majority of police actions brutality, or only a miniscule fraction? This is the crucial question, and a site like this provides no insight at all. (or so I imagine, since site is down) If you want to fan the flames, though, add a section for protesters savagely kicking unconscious victims in the head.
There is a very large difference between random protesters committing violent acts and government sanctioned organizations with the legal right to shoot and kill implementing a wide spread program of violence and brutality. If you cannot see the difference, then you are not looking. If an officer observes another officer committing a crime and does not intervene then that officer is corrupt. At each of these police brutality incidents there are often a number of officers observing and not intervening.
When the system designed to enforce the law routinely breaks it without punishment then the system is broken and needs to be rebuilt.
