buy-and-bust operation

The officers mill through the streets, stopping cars, checking out-of-town licenses, doing buy-and-bust operations.

The two men worked together on a buy-and-bust operation lasting from the afternoon until early the next morning, Mr. Trapani said.

He was killed in the midst of what many consider the most dangerous work police do: what they call undercover buy-and-bust operations.

The buy-and-bust operation was actually part of a murder investigation, the police say.

The buy-and-bust operation had been a part of an investigation into weapons sales that had been going on since January.

Detective Lopez, 35 years old, was killed in a classic "buy-and-bust" operation, in which an officer poses as a potential drug buyer.

He was sent there after being arrested in May 1998 for selling drugs to an undercover police officer during a buy-and-bust operation.

A 21-year-old man was shot by the police last night during a buy-and-bust operation on Staten Island, the police said.

The plainclothes officers' operations in the park have primarily been "buy-and-bust" operations.

The shooting underscored the dangers in undercover buy-and-bust operations, which are a staple of police efforts to crack down on the illegal drug trade.
