Word is that gun sales are up in Colorado since the movie theater attack Friday. The Colorado Bureau of Investigation says they processed 43 percent more background checks for gun sales over the weekend and many Denver area gun stores are reporting increased sales and registrations for classes. Many classes have filled up, and some stores are adding more gun instruction classes just to keep up with the demand. This isn't the first time gun sales have gone up after an attack. After both the Tuscon shootings in 2010 and the Virginia Tech attack in 2007, gun sales in the areas near the tragedies spiked. Not only do sales increase after an event like the Aurora shootings, but firing range usage skyrockets as people who already own a firearm take the time to sharpen their skills with their weapon. Are people reacting properly by buying guns after the attack? Do you feel less safe than you did before the attack on Friday?
