Chesapeake police have a nose for pot

CHESAPEAKE, Va. (AP) - Chesapeake police have a nose for marijuana.

But some defense lawyers are questioning the police's practice of pulling over vehicles based on an officer smelling the drug.

According to court documents, an officer said at a preliminary hearing last year that officers drive with the vents of their patrol cars open. Outside air is pulled directly into their faces.

Assistant Public Defender Matthew Taylor says that the idea of officers driving behind a vehicle and being able to smell marijuana is preposterous. Taylor made an unsuccessful bid last week to get a search of his client's car dismissed.

ACLU-Virginia executive director Kent Willis expects more legal challenges in the future.

Chesapeake Police Department officials declined to comment.
