Operation Sudden Fall

The undercover officers started to appear at San Diego State fraternity parties about six months ago.

The real students appeared to accept the pretend ones -- most but not all of whom were men. On a campus of 34,000 students, blending into the crowd was not difficult. Neither was collecting evidence of drug dealing and drug use.

On Tuesday May 6th, authorities announced that 96 young men -- including 75 students -- had been arrested on a variety of drug charges as a result of Operation Sudden Fall.

A criminal justice major was arrested on suspicion of possession of cocaine. As he was being arrested, he asked officers if this would hurt his chances for a law enforcement career, officials said.

About 20 of the arrested students were involved in selling drugs, authorities said. The remainder were arrested on suspicion of possession. About 130 drug purchases were made during the investigation, both on and off campus.
