Gun control advocates like to pretend that the “good guy with a gun” thing is just a gun rights talking point, but over the weekend, their narrative got busted once again:

More from the Washington Free Beacon:

While the armed father was in the Birmingham fast-food restaurant with his two sons, a masked man entered and began shooting. The father then returned fire on the attacker, ultimately striking and killing him. The father and one of his sons were injured in the attack. No other injuries were reported.

“It’s really sad an otherwise positive day had an ending like this,'” Birmingham Police spokesman Sgt. Bryan Shelton told AL.com. “Earlier we had such a spirit of celebration in the city because of the events going on and now families are having to deal with the tragedy of loved ones who are hurt or killed.”

Sgt. Shelton said the father acted in defense of himself and his sons.

“Right now, it appears the victim made a decision that cost his life and the father made a decision that preserved his and [his] children’s'[sic] life,” he told the publication.

This McDonalds employee is grateful for the man’s quick thinking:

God bless that father.

They really are out there.
