Like Mike Brown? The maority of police shootings have been justified. Not all, but so many that calling them all murders and pointing the wrong fingers does nothing to realize the situation 

The problem isn't why so many young blacks are getting shot by police, but why are so many young blacks engaging in crime.  And in the clear case of Michael Brown, violently resisting arrest?  Michael Brown tried to kill a cop and has been martyred by the black community. This in itself is divisive.
