SIOUX FALLS, S.D.(KELO)- The men and women in blue say they’ve talked until they’re blue in the face…but they wonder if anyone’s listening.

Police Chief Jon Thum wants to change the trends on car thefts.

The police department is launching a 50-thousand dollar campaign to try to break the trend.

The theme is “Lock it and Pocket”…meaning always lock your car, and always put the keys in your pocket.
