When Elton Simpson and Nadir Soofi opened fire outside the Muhammad cartoon event Sunday night in Garland, Texas, they were killed by a traffic cop working after-hours security for the event to pick up extra money.

The officer who killed them was armed only with a handgun.

According to Fox News, Garland Police spokesman Joe Harn said the unnamed officer “probably saved lives.” He added, “His reaction, and his shooting with a pistol, he did a good job.”

Harn said Simpson and Soofi were armed with “assault rifles” and wearing body armor, yet the officer was able to take them out.

“Four SWAT team members with high-powered rifles also fired at the suspects,” but CNN reports that both were killed by the traffic cop armed with a .45 caliber Glock.
