ExpertNovice (not quoting because it would get to be a huge mess):
I think the media and laypeople are getting awfully carried away about the absence of DNA or latex residue. It's not as though (if we temporarily assume this accuser was raped) the rapists couldn't have pulled out, failed to ejaculate, or used non-latex condoms. I can't say I've ever worked on a case in which latex residue was found in a rape kit, but I've definitely worked on cases in which rape kits found no DNA nor latex residue.
I have actually prosecuted (well, overseen the prosecution of) a case in which a rape accuser was too drunk even to know she had been raped, then remembered it months later. It turned out she was right that the guy had had sex with her, but he was acquitted of rape (though I still feel he was guilty). Awful mess of a case.
I regard the conjecture about a website containing a list of the wealthiest Duke lacrosse players fanciful, but agree it would be relevant IF she had seen it, and IF she accused some of the wealthier members on the team. No idea if there's any evidence of either of these things, though, and frankly I find it implausible that such a site ever existed. Keep in mind, they hired her - it's not like she pushed her services on them in order to claim rape by a member of the team.
I don't agree, _at_all_, that these guys are being presumed guilty. If anything the reportage seems to be aggressively oriented toward proving that she's lying. That does not, of course, mean that the suspects are not being put through a dreadful, horribly unfair process if they are in fact innocent. It's a crappy deal all around. If they didn't do this, I have total sympathy with them, because this is a terrible thing to have to go through.
