you seem to be misusing the word "justification"That's a lame justification for shooting cops....and it shows why cops shoot thugs.Shooting unarmed blacks destroys the cops integrity.It also destroys Eric Holder and Obama's integrity as unbiased. They have just thrown gas on the fire of racism. This is a real setback for ending racism. It has only served to inflame bigotry of both whites and blacks.
It may be another two hundred years before another black is in the White House.
