Did you even see his interview with the BBC? Legally would not say anything about his hiring of prostitutes. No medical evience of the torture he claimed. The only hard evidence that was provided were CCTV tapes of him going into local massage joint. You would think that if he didn't obtain the services of sex workers he would come out and say it. Interesting that the British also let him go.
I've seen those videos. You have to be kidding if that's sufficient evidence to say they are being shipped off to Chinese black camps. As for the alleged rapes - the evidence is even more lacking. The primary source used is a facebook account using a pseudonym who claims he's an emergency doctor who then says he "swears" that he's telling the truth.
Everyone needs to be held to a basic standard of logic and scrutiny, not a double standard simply because one might agree with the ideals of a group. There are numerous ludicrous claims on the government and police side. But the same stands for protesters as well.
