But veterans, many of whom have combat experience, shed light on the difficulty of performing their duties under extreme duress, as one may experience in a combat situation.
"Those who study the effect of fear in combat, this isn't that unusual,"
said Mark Hertling, a CNN contributor and former Lt. Gen. in the US Army. "While soldiers/security are trained to run to the sound of the guns...not all do for a variety of psychological reasons."
"It happens more often than most would think, and it's part of human nature." Hertling said.
Paul Szoldra, editor-in-chief of Code Red News and a former infantryman in the Marine Corps, noted that even service members acted differently in combat scenarios.
"I know people are dumping on the school resource officer who didn't go into the school, but the sad fact is some people freeze in combat situations,"
Szoldra said. "It happens with cops and soldiers, training be damned, especially if it's their first time under fire."
"As much as we'd like a convenient foil to blame, and this cop certainly provides that, I would imagine he's going to carry the guilt of his choice to not go in for the rest of his life," Szoldra
continued. "Ultimately, the blame for this rests on the shooter alone."
Nate Bethea, a writer on veterans-related issues and a former US Army infantry officer,
criticized those who had no combat experience and were quick to condemn Peterson.
"When I was in Afghanistan we had a platoon in my battalion lose a guy during a shootout, and the whole team froze," Bethea
said. "These were trained airborne infantrymen whose fellow soldier's life was in danger. They eventually got back in the fight, but yeah."
