Vallejo police Chief Andrew Bidou discusses the Sunday, Oct. 16 shooting shooting of Andrew Powell, 41, during a media conference at Vallejo City Hall on Monday, Oct. 17, 2016. A gunman targeted two Northern California officers who were taking a break at a coffee shop in an ambush that was foiled when his gun malfunctioned, a police chief said Monday. The man, who was wearing body armor, fled when he could not get his weapon to fire, and the officers gave chase, shooting him three times, authorities said at a news conference. He is in critical but stable condition. (AP Photo/Chris Preovolos via the San Francisco Chronicle)
