Isn't it time we profiled veterans?

Perhaps because of the violent and stressful nature of their work and their training that helps them ignore the natural human aversion to taking a person's life, veterans have been involved in numerous acts of violence both here and abroad, whether it's Tim McVeigh, Nidal Malik Hasan, or the DC snipers attacks on Americans, Lee Harvey Oswald's ination of President JFK, or the Blackwater murder cases, the numerous cases of murder-suicide, and of course many reports of war crimes against whatever innocent population-du-jour we have declared war on, isn't it clear that veterans pose a threat in excess of average citizens? Shouldn't we profile them and put them on watchlists to better protect ourselves?
