“Anytime there is a tragedy around the United States, where people perceive that had they been armed they could have made a difference, it increases our feeling of vulnerability,” said Charlie Strickland, co-owner of the Talon Training Group gun range in Tallahassee. “In our country, you’ll see a corresponding increase in the purchase of firearms and an increase in training.”

Last year, more than 885,000 background checks were conducted for gun purchases in Florida, a record number.

The state is on track to break that record in 2016, as month-to-month background check comparisons show an increase for every month when compared to the same time in 2015.
