TUSCALOOSA, Ala. — The looters come out at night in Tuscaloosa, Ala. So does the curfew patrol.

With a long, broad band of this city laid waste by a tornado that killed at least 45 people and destroyed hundreds of homes and businesses, Tuscaloosa police have been working 12-hour shifts without any days off just to keep order.

Mayor Walt Maddox imposed a curfew from 8 p.m. to 6 a.m. in the ravaged areas, where the power remains off, so officers are now patrolling pitch-black, storm-tossed neighborhoods they once knew by heart to keep the storm's toll from getting any worse.

In the days after the twisters, residents complained of widespread looting.

Since then, Gov. Robert Bentley has sent in Alabama National Guard troops to staff checkpoints in the mostly heavily damaged areas.
