"1,052 incidents from 2013 through Dec. 2, 2015"

This doesn't include the recent murder suicide of wife and three kids by the husband in Hubbard OR. It doesn't include the 3 women daily who die as a result of domestic violence or the incidentals like the guy who stuffed his parents in the freezer in Springfield or the guy who killed his dad, tried to kill his mom and plowed down two people with his car.
