Simple fact is,,,,some people shouldn't be police officers. The guy who shot  Castile panic and for some reason so did the guy who shot this individual. Just because you wear a police uniform, doesn't make that person a Dick Tracy. I worked for DOC Alaska for 27 years and there were few individuals I knew who wore the same uniform I did. that shouldn't be working....simply because they were either cowards,  cheats, mentally weak or criminals without a record (yet). Most don't last long at all. Rotten apple lies in every organization or every group.  Not all soldiers will run toward the sound of combat....few will sneak back to hide. That officer who shot that therapy worker......should be terminated, eh?
