In a Dallas Morning News article titled “Narcotics unit has troubled past,” Robert Tharp reports on a massive but fruitless polygraph dragnet conducted by the FBI in the Dallas Police Department’s narcotics unit in 1996. Excerpt:
The FBI investigated the narcotics division in 1996 at the request of former Chief Ben Click following the disappearance of $50,000 from a narcotics bureau safe inside a locked office.
More than 120 officers took polygraph tests and submitted to questioning, but no suspects were ever caught. Following the investigation, department commanders revised the division’s procedures, tightening access to money in the safe.
