Columbia Hides Evidence in Professor Case

A noose was hung on the door of a professor at Columbia Universiy, which prompted an investigation by the Justice Department. Speculation is swirling that it was a fellow professor whom the victim had a falling out with. This is the part that is very odd:

Columbia University has refused to turn over security videotape that could help identify who hung a noose on a black professor's office door, police said Thursday.

Investigators began asking on Wednesday for tapes from cameras in the building, but have been rebuffed by administrators, said Paul Browne, the New York Police Department's top spokesman.

He said police will have to get a court order to force the school to provide video they believe could crack the case.

Why would Columbia not release the tape? Is it because the tape clearly shows the other professor as the culprit? Does it show nothing? Or perhaps it shows the perp and the he or she is someone that the university doesn't want identified such as a black person or someone else?

Something is highly fishy here and Columbia has had more than their share of bad press. Why are they needlessly adding to it?
