In 2.5 seconds, police shooting ruins lives

All it took was 2.5 seconds.
Two-and-a-half seconds for West Valley City, Utah, police detective Shaun Cowley to assess what he perceived as a threat, pull his 9mm Glock pistol from his holster and fire two shots.
Two-and-a-half seconds for one of the bullets to pierce a driver's side car window and enter the left side of Danielle Willard's skull.
Two-and-a-half seconds to take Willard's life.
Two-and-a-half seconds that changed Cowley's life.
"The shooting cost me everything," Cowley says. "You make a split-second decision about whether you go home that day and someone else does not. That's a heavy burden."
