Great news! Hillary will be closing the wrong side on this one, and people will see through it.
No, they won't. Most leftists are thoroughly conditioned to believe the leftist narrative. I can guarantee that the majority of strong Democrat supporters believe the narrative that those thugs were innocent black men minding their own business when some racist cop, Hispanic guy, what-have-you, decided to use them as target practice.
This is the narrative that we have to defeat, by pounding over and over that these thugs were thugs, behaving like... thugs. Decent black men, as a rule, are not sought out for target practice (and if that were to happen, the outrage would be deafening).
