Odd that Columbia University isn’t cooperating with the police in their investigation of a racial incident. The university refuses to hand over video tapes that could identify the wrongdoer. I wonder why that is? Perhaps it’s yet another racial hoax on campus? Or perhaps the perpetrator is another professor? It sounds more like the latter according to the reported victim:

Police believe the noose was placed on the doorknob of Constantine’s office at Teachers College — Columbia’s graduate school of education — Tuesday morning, when a colleague spotted it and notified authorities.
Police declined to discuss possible motives or suspects.
Constantine, 44, told police there was “ill will” between her and another professor who had replaced her while she was on an extended leave, a police official said.
But the official, speaking on condition of anonymity because the investigation had not been completed, stressed that the dispute was only one possible lead, and that police were also looking into whether “disgruntled students, anyone upset with grades” were involved.

Either way, I bet if the perpetrator were the head of the college Republicans, the tape would be on YouTube by now.
