Maybe if that "outrage" was turned more towards the blacks that keep killing other blacks, maybe there could be some progress.
But NOOOOO, let's just get outraged at the white guy.
Those guys won't put their stuff in the media unless they put it on Facebook.
Sure, there is outrage at the Democrat controlled and created war zone in South Chicago. A lot of gun control measures are 'justified' by statistics generated by that slaughter. My being outraged by that won't change it, I'm just a white guy in North Dakota, another 'flyover country hick' to city folks who don't know me. The people in Chicago have to change that mess there. The Government can't--even though it helped create the problem (how's that Great Society working out for y'all?).
All that said, the "white guy" you are talking about here is not some billybob slackjaw from Buttscratch, wherever, he is a supposedly socially sophisticated person running for the office of President of the United States of America. If he can't avoid the sort of self-serving nonsense which he ladled on a tragedy without apparent basic consideration for the feelings of friends and family of the victim, is he really the person you want in the Oval Office?
A tweet of his condolences for the family might have been a bit more apropos, ya think? Just the source would have been sufficient for the ad value. Bragging that blacks are going to vote for him because some innocent was gunned down in a turf war isn't likely to do anything but draw fire. Sometimes acting like a bad schoolkid just gets you in the corner with a dunce hat.
