Detroit's 'Shotspotter' contract up for renewal

The four-year contract expires Tuesday, and Detroit police are pushing for an extension. Police say ShotSpotter technology allows them to do their jobs better, collect more evidence, and respond to scenes faster.  Detroit police have made it clear they often don't get 911 calls.
