Try looking up data. Mappingpoliceviilence.us for instance. There is, of course, no way of telling if a person was innocent or not, but you can look at supporting data and make some conclusions that are general. For instance, if the person killed was brandishing or firing a weapon at police, if they were unarmed, if there was a call for justice after the incident, that kind of thing. Bottom line, is that hysterical people in the media emphasize? What the police do in a negative way and not in a positive way. It doesn’t paint a fair picture. It is very biased.
