Following the attacks in Paris, gun sales are booming across the United States, not only from those who were already armed, but first time gun owners as well.

Concealed carry classes at Texas Guns “have doubled in the last week,” and the Limestone, Alabama, Sheriff’s Office reports witnessing its “biggest spike in permits” after the attacks on Friday, Breitbart reported on Wednesday.

The gun shop in San Antonio has also seen a 30% increase in sales.

"A normal firearm is about 7 to 10 rounds and what has been selling this last week is 30, 40, 50,” Jerry McCall, owner of Texas Guns told the local Fox affiliate. "I am 67 and I have people coming in their 70s and 80s who say they have never owned a firearm before but I think I need one in the house now.”

In Alabama, gun dealers have seen a similar response.

"We were busy right out of the box," Russell Durling, owner of Last Resort Guns in Madison County, Alabama, told local station WAFF. "The truth of it is, when America is scared, America buys guns.”

The boom in sales and permits after times of tragedy is interesting, and you cannot help but wonder who benefits from terror more — ISIL extremists or the NRA.
