Warning: this is quite a shocking read about what was going on in frat houses at UVA, and the administrations utter failure to handle it.

I don't think it invalidates the whole piece though, and the UVA administration's behaviour closely resembles those of other universities that have recently become public, so it still seems credible.

I agree that the journalist behind the Rolling stones article should have heard the alleged rapists. It's bad journalism not to, but I seriously don't think the story would benefit from hearing them unless someone actually would admit guilt.
What really struck me as weird in the Reason article is how the colleges are involved in rape cases. I suppose it's PR but how on Earth are they able to expel rape:y students on their own without going through the justice system.
I'm not sure why that points to gaping holes in the UVA case. While some of the criticism is valid, frankly I find the overly sensationalist deconstruction of the original article for the sake of attention and page impressions rather distasteful.
