New Jersey's Brookdale Community College says it is investigating after sociology professor Howard Finkelstein was caught on video shouting the f-word at a student in class.The student he was shouting at, Christopher Lyle, says it was one of many times Finkelstein has attacked him in class for expressing conservative ideas. The student who shot the video, Joey Smith, says he was tired of Finkelstein singling out Lyle for abuse. "He is basically just lecturing this one student for the whole period," Smith said.
