 [Mapping Police Violence](http://mappingpoliceviolence.org/) just released [their 2015 Police Violence Report](http://mappingpoliceviolence.org/2015/), along with the data supporting it. 
 
-One of the most stunning conclusions of the original report is the finding that community violence does not predict police violence. This disproves a common narrative that police are simply responding to violence in kind, and suggests that department policy plays a role in police behavior.
