After holding out for more than a day, Columbia University will give New York police surveillance video that could yield clues on who left a noose on a professor's door, the New York Daily News reports. The school had told police—investigating what they're calling a hate crime against Professor Madonna Constantine—they would need a subpoena to get the tapes.
"It's unfortunate because it adds a time-consuming step to the investigation," an NYPD official told the News. Columbia colleagues found the noose—a symbol of racist lynchings in the South—on Constantine's door Tuesday. Constantine teaches race relations at the Ivy League school; police say they don't yet have suspects. Columbia also agreed to turn over names of students in Constantine's classes.
