DA won't file criminal charges in Vegas police shooting of unarmed Gulf War veteran in 2011

The district attorney in Las Vegas says mistakes were made, but no criminal charges will be filed against a police officer who shot and killed an unarmed, disabled Gulf War veteran in his car in December 2011.

Clark County DA Steve Wolfson issued a report Thursday saying that Officer Jesus Arevalo thought he was shooting in self-defense when he opened fire with an assault-style rifle, killing Stanley LaVon Gibson.

In fact, what Arevalo heard was another officer firing a beanbag shotgun to break a side window of Gibson's vehicle.

A grand jury previously refused to indict in the case.

Attorney Cal Potter represents Gibson's widow, Rondha Gibson, in a federal lawsuit accusing Las Vegas police of civil rights violations.

Potter says he didn't expect that the county DA would prosecute.
