Columbia University won't turn over the video showing who hung the noose on the black professor's door.

So. The evidence is: Columbia University won't turn over the video showing who hung the noose on the black professor's door.

Infer.

UPDATE: Decision reversed. Good. It's absurd to report this to the police and then not cooperate. If you want to keep it private, resolve it internally.

ADDED: This Daily News article has a picture of the noose hanging from Professor Madonna Constantine's doorknob. There's also some info about her colleague Professor Suniya Luthar, whom Constantine is suing for $100,000 — some defamation case that we'll need to hear more about. We're told Luthar is not a suspect, but right under the picture of the noose, the newpaper has a picture of Luthar with worried expression on her face. In the photo, Luthar is caught wearing an oversized "Phantom of the Opera" T-shirt and short shorts. This exposure of Luthar — we see her thighs — seems really unfair.

AND: By contrast, this long NYT article about Constantine doesn't even mention Luthar's name. We're told only that Constantine has "filed a defamation lawsuit against another professor in her department" and that she "declined to elaborate on the case." (I want to add that it strikes me as inconceivable that Luthar is the culprit here.)
