I've been lurking from the US. I have to admit I don't recognize a lot of the names, let alone figuring who the initials are!
I've checked the US gossip sites and a big fat 'bupkis' there.
I do know who RB, DW and couple of others on the 'list' are and IMHO if this story is about them and sexual escapades I don't get why it would rate a whole 90 minutes, even if there are allegations of underage or coerced victims. Hell, I think Epstein only got an hour on various US network news shows (Dateline, 20/20 etc).
But if there is an allegation of the bribes taken by authorities, or of an official police coverup or intentional 'mis-handling', that would rate 90 minutes.
EDIT: Ah, I see it's dropped..just Brand then? I still don't get how a 'used to be' media figure rates a 90 minute program investigating his past (potentially abhorrent) behaviour. I hate to sound 'tin foil hatty', but does he have some kind of information that could be damaging to someone and they want to discredit him. Or is it just a rather slow news day. Because I'd say compared to Epstein and Savile, an allegation by 5 victims appears to be somewhat small beans.
Not that I'm discounting the pain and fear suffered by his victims, not at all. It should definitely be publicly known.
