“Are military veterans more likely for shooting sprees?” The San Diego Union-Tribune asked last year, citing eight occasions when a veteran of one of the wars fought since September 11, 2001, perpetrated a mass killing.
Experts cautioned against sweeping conclusions, stressing that there is no evidence that veterans of the wars in Iraq or Afghanistan are any more prone to violence than the general population; the overwhelming majority of those who return home from war are thriving.
“Combat veterans, on the whole, are not going to be lethally violent,” said Shoba Sreenivasan, a University of Southern California psychology professor who was the lead author of a 2013 paper examining the topic. She noted that a small segment of combat veterans may be triggered to commit violence because of their battle experiences. These individuals often have mental or emotional issues other than war-related post-traumatic stress disorder.
“There are some people—a very tiny, tiny percentage—whose combat experience creates some mental instability, along with other factors like drugs and alcohol, that then may contribute to lethal violence stateside.”
Thomas Burke, a pastor in the same US Marine Corps regiment where the Thousand Oaks killer served, spoke to CNN about their time in intense combat. “PTSD doesn’t create homicidal ideation,” he argued. “We train a generation to be as violent as possible, then we expect them to come home and be OK. It’s not mental illness. It’s that we’re doing something to a generation, and we’re not responding to the needs they have.”
If so, what are those needs? The killer tried college but failed to earn a degree. He was reportedly a patron of the bar, but obviously turned on that community, if it was one for him. Absent better answers about whether this man was among the tiny percentage who wouldn’t have killed at home but for being sent to kill “over there,” or what exactly would have altered the course of his life once home, it seems safe to at least conclude that his combat experience made him a more skilled assailant.
And whatever the factors in this particular case, it is past time that America embarked on a sustained experiment in waging foreign wars only as a last resort—and did more to support those it sends abroad to fight when they come back home.
