In fairness, my best mate works in TV journalism for BBC and he says they do kind of choose their targets. I'm not talking about Brand specifically..
But the way these documentaries work is they basically decide who to go after, maybe on a tip off, and then they dig from there, I.e journalism. But when they say "6 women come forward" - well not exactly, they go through your past, start digging and approach the women and offer them incentives to talk. I mean, it's not realistic to think 6 women that don't know each other from incidents over the course of 20 years all suddenly contact the same production company at the same time. They're targeted and approached and offered incentives to give content on the person the production company is making a documentary on.
Of course, that's all OK, it's what journalism is. But what that also means is they pick and choose who to go after. That's why so many cases have been hidden over the years and some haven't.
So from there, you have to question why some people get brought to light and some get protected.
Whether you believe its a witch hunt against people certain political views or not, there's absolutely no denying that the media and corporations are selective on who they target and who they don't.
Personally I think Brand's past is catching up with him and there's a fair bit of truth here, but I'm just talking generally about how these things work.
