A spike in traffic complaints sent Lakeville Police Chief Jeff Long to social media for help.

What followed wasn't the usual online firestorm of complaints or cheap quips.

Instead, the comments on the department's Facebook page allowed Long and his officers to identify the city's biggest traffic problem areas and create a spreadsheet to document priorities.

"It isn't just the cops hiding around a tree trying to catch people speeding," Long said. "We're actually going to the spots our residents are telling us they want us at."

And, he said, it's leading to arrests for other crimes. At the end of May, Long tweeted that four traffic stops in one evening ended in the recovery of a stolen car, a drug arrest and two DWIs.
