It appears to me that the Dallas police force has, unfortunately, and undeservidly reaped the whirlwind that has been sown over so many years by so many police officers who somehow came to believe that wearing a badge gave them the right to shoot black (and white) men with impunity. While I have no doubt that officer fear (it does not really matter whether real or imagined) drives a good deal of these killings, the underlying cause is still a culture of entitlement and coverup within police agencies.
