Imaginations can do amazing things. They've been interviewing the victim's co-worker at the school where he worked. There's no indication that this guy was anything other than clean. Law abiding citizen.
To be fair, the guy could have been the worst dirtbag on the face of the earth and his friends and family will still say he was a pillar of the community and a heck of a guy, then come out with stories about how he bought ice cream for the neighbor kiddies and carried grocery sacks for old ladies.
But that information would have come out by now, I would guess. It usually only takes about three seconds for the shot guy's history to start going around social media.
Alton Sterling, for example. We know from his arrest record that he was a raging ####bag. Drugs. Guns. Rape. Violence. No great loss and anyone who is mourning him is an idiot - Beyonce, I'm talking to you. They're calling him a "salesman", which is like calling that hooker who accused the Duke team a "dancer". Sterling was a bootlegger, which is also against the law in addition to all his other more pertinent violations.
Philando Castile, on the other hand, is coming up clean so far. He has a couple of parking violations. Oh, and he got busted once for not wearing his seatbelt. To lump him in with the likes of Alton Sterling, Michael Brown, and whatever other ####bags the cops took out of our misery is laughable and ignorant and racist bull####. He does not belong in that group.
