Milwaukee expands ShotSpotter program

A Milwaukee program used to fight crime is expanding.

It's something you'd picture on The Jetsons. A piece of futuristic technology already being used by the police department, called ShotSpotter, is expanding 8 square miles. The total miles covered will be 11 miles. It will focus on Milwaukee's central, north, and south-side.

Alderman Willie Wade says since it was rolled out in 2011 it's been effective in fighting crime.

Alderman Wade says, \"They don't know we have this technology, and it's catching them by surprise, so we are catching the criminals before they can play defense on it.\"

ShotSpotter uses audio sensors to 'listen' for gunfire and then it alerts police. The new sensors will be put in parks across the city. The city used a grant to help with the expansion.
