No, it was after, and IIRC, during the incredibly long active legal proceedings.
Rivers was not a founder of Camp Trans; not even Graham is claiming that.
Graham's criticism is that Rivers, a key figure in Camp Trans, murdered Michfest attendees, and it's disgusting that Ronson didn't cover that.
There's no evidence to support claims that Rivers was an organiser of the event, a key figure, or even to confirm which years they attended.
The only evidence of their involvement in Camp Trans is a report of a 2000 demonstration featuring Rivers.
There's no evidence that supports the claim the victims ever attended camp trans.
I mean, if there is evidence to back up his claims, Graham should present it. Expecting Ronson to report a sequence of events the way Graham feels it should be reported, and to unearth evidence Graham suspects exists but is too lazy to dig up himself, is ludicrous.
