Your concealled weapon doesn't do you any good...

...if you leave it in your car.

Nashville Police spokesman Don Aaron said the gunman shot one woman, who was leaving the church, in the parking lot before going inside.

“One of the church members, upon seeing the gunman do this action, ran up to confront him, and was pistol whipped by the gunman,” Aaron said during a press conference taped by the Tennessean.

That church member then went to his car, where he had a gun covered by his concealed carry license, and went inside the church to confront the gunman again.

UPDATE:

Regardless, he still stopped a mass shooting. Good work.

Engle confronted Samson after he entered the church. Samson pistol-whipped Engle. After Samson shot himself, Engle went to his vehicle, got his own weapon and held Samson at gunpoint until police arrived, police said.
