Authorities speed gun fails

WATERLOO (KWWL) -- Authorities weren't able to keep up their speeding enforcement, because the batteries died on a laser speed gun they were using Thursday morning.

The State Patrol has been focusing on Interstate 380 and Highways 30 and 100. They've been using newer laser guns which can pick out speeding cars in groups of vehicles.
