As is normally the case, the details of the situation are not clear, but it does appear that the officer in question, a Riverside sheriff's deputy, discharged his or her firearm. There is nothing to indicate that the robbery that Soto is being accused of involved weapons of any kind, so one must certainly question the use of (potentially) lethal force against someone who was fleeing.

JURUPA VALLEY: Deputies shoot at, arrest robbery suspect
JUNE 1, 2014 BY STEPHEN WALL
A Riverside County sheriff’s deputy shot at but did not hit a robbery suspect who the deputy said reached for his waistband during a foot chase Saturday, sheriff’s officials said.
The suspect – 28-year-old Rolando Soto, of Fontana — was booked into jail on suspicion of felony robbery, jail records show. Bail was set at $30,000.
Deputies assigned to the Jurupa Valley station responded at 6:07 p.m. to a call of a robbery in progress in the Denny’s restaurant parking lot in the 6800 block of Valley Way, according to a Riverside County Sheriff’s Department news release.
Deputies saw Soto running from the location and chased him into the backyard of a home in the 7100 block of Valley Way, authorities said in the release.
When confronted by deputies, Soto reached for his waistband and was shot at but not struck, the release said.
Authorities said Soto assaulted and robbed a man of his cellphones while the victim was sitting in his vehicle in the restaurant parking lot. The victim sustained a minor injury, according to officials.
The deputy who shot at Soto was uninjured and has been put on administrative leave, per department policy, the release said.
