Batman massacre boosts gun sales

Gun sales have surged after the Batman cinema massacre amid fears that politicians may use the shootings to seek new restrictions on owning weapons.

In Colorado, where Friday’s shooting killed 12 and injured dozens, gun sales jumped in the three days that followed. The state approved background checks for 2,887 people who wanted to purchase a firearm – 25% more than the average Friday to Sunday period in 2012 and 43% more than the same interval the week prior.
