Colorado Gun Sales Spike After Aurora Theater Shooting (POLL)

Less than one week after the mass shooting which left 12 dead at a movie theater in Aurora, Colo., the Denver Post reports background checks for people wanting to purchase firearms in the state have jumped more than 41 percent.

"It's been insane," Rocky Mountain Guns and Ammo employee Jake Meyers told the paper, saying there were already 15-20 people waiting outside the store when he arrived at work Friday morning, just hours after the massacre.

Over the weekend, the Colorado Bureau of Investigations approved 2,887 background checks for people seeking to purchase a firearm, according to the Post.

The spike follows an example set in Arizona, where gun sales soared following a shooting which left six dead and 13 wounded, including Rep. Gabrielle Giffords, according to Bloomberg.

That report cited data from the Federal Bureau of Investigations, which found one-day sales of handguns in Arizona jumped 60 percent two days after the shooting.

Gun stores aren't the only ones seeing a bump in the wake of the tragedy. The Street reported Tuesday that shares of publicly traded firearm companies "have outperformed the broader market during the past two trading days."
