Violence is counterproductive. The police are necessary to protect you from psychopaths like me who would like to eat mushrooms and dance in your skin. These things do not fix the problem. Pretending that the other half of the population is satan is stupid.
Anyway, one was shot by police, one had a heart attack, one had a stroke, an one had an undisclosed medical emergency. That leaves one officer who was beaten with a fire extinguisher.
So, going by criteria established earlier this year it was mostly peaceful.
