DETROIT -- Police Chief Ella Bully-Cummings kicked off a traffic enforcement blitz in two neighborhoods plagued by dangerous motorists in response to Mayor Kwame Kilpatrick's vow in his State of the City address to crack down on crime.

The stepped-up patrols began Thursday and will last through Sunday.

"This is about zero tolerance for people out there driving and drinking," Bully-Cummings said. "We are going to take the city back, not only from people committing crimes but those that are drinking and driving."

The chief's remarks were made at a Thursday afternoon roll call for a platoon of 20 traffic enforcement officers, as the call to action kicks off in time for St. Patrick's Day weekend.

The chief and the platoon commanding officer, Lt. Rafael Washington, also stressed that as part of the assignment, the officers in the marked cars were to be as visible as possible in the neighborhoods.

"If you don't have a traffic stop, make sure you go down the adjacent streets in the neighborhoods," Washington said.

The officers will patrol areas from Grand Boulevard and Woodward west to Grand River and Seven Mile from Telegraph to Greenfield.

A Detroit firefighter was killed last month in the New Center area when his rig was hit by a speeding SUV that ran a red light.

Another fire truck was hit by a speeding driver earlier this week in the Telegraph-Seven Mile area.
