Devin Patrick Kelley, who recently killed 26 at a church in Sutherland Springs, TX, was dishonorably discharged from the Air Force in 2014 for assaulting his wife and child. He was therefore prohibited from purchasing and owning firearms, yet he was still able to obtain a Ruger AR-556 rifle from gun shop.

There was another infamous breakdown of the NICS system a couple years ago: Dylann Roof was able to purchase a Glock handgun months before he shot up a church in Charleston, SC.

The FBI says its background-check system failed, mistakenly allowing the man who allegedly opened fire inside a South Carolina church last month to purchase the gun he used in the rampage.

"We are all sick that this has happened," FBI Director James Comey told a small group of reporters in Washington today. "We wish we could turn back time."
