This Globe and Mail story tells of how the Edmonton Police were trying to nail an Edmonton Sun columnist, one who had been critical of them, for drunk driving.

An excerpt:

It's a scandal ripped from the tabloid headlines — a veteran newspaper columnist who takes on the police force finds himself under surveillance, the victim of a sting operation that even ensnarled the police commission chair.

Since November, Edmonton has been abuzz with the case of Kerry Diotte, the Sun columnist who angered police by writing about what he said was their propensity for high-speed chases.

Edmonton police hoped to catch him driving while impaired one night, only to apparently be foiled when he took a cab home from a social event attended by dozens of journalists and local politicians.

The headlines took another dramatic turn yesterday, when transcripts of police radio transmissions emerged revealing officers saying they would just have to bag their "target" on "another day, another time."

Police have said all along it wasn't a sting — just a tip they dutifully acted on. And their chief backed the statement, even though he recently expressed doubt about the quality of the tip that led police to the bar in the first place.
