So, I looked at tit and discussed it. Thats reported "attacks". Not verified, so it's worthless. Is that thing vetted beyond the initial reports? If not, then it means nothing.
And about the alleged suspects. These are not suspects, just the only people they managed to find anywhere remotely nearby during the time in question.
So, we have no facts verifying the attack. We know he got hurt, there are medical records confirming that. Everything else is open to question. We don't blindly believe his because the probability of what he says happening actually happening is pretty low. As we have said repeatedly, do you believe that some bleach and rope toting racist homophobes, who somehow watch a show based on successful black people who accept a gay black singer also just happen to be roaming around downtown Chicago at 2am looking for random black gays to attack. And these magically lucky racist homophobes who just happen to enjoy a show almost designed to be unwatchable by racist homophobes just happen to stumble across this guy.
Sorry, but like killer cops, the incidence of racist homophobes in the general population is pretty low. So thats why we doubt his story.
