Behind a paywall, alas, but very detailed, with extensive quotes from Ludlow and the student.
UPDATE: A philosopher elsewhere writes: "Why don’t you open comments? Much of what has been posted has been shown to be wrong. People should face up to that. FP hasn’t linked to it and Justin W is trying to bury it." I haven't really followed coverage on other blogs (though it would not be surprising if my correspondent's allegation were accurate), but I will open comments. No naming names of students and I will edit for relevance.
