The state Senate on Tuesday passed a bill that would give the department $175,000 in state aid to expand the ShotSpotter program, a system of audio sensors that captures the sound of gunshots and transmits their location to officers.
The system currently covers 3 square miles. Police want to use the state money and a matching $175,000 in the Milwaukee County budget to cover 10 square miles.
The Assembly passed the bill overwhelmingly in February. The Senate's unanimous vote passing the bill now sends it to Gov. Scott Walker.
