“[Dylann] Roof turned 21 in April, and a short time later he had a gun,” cnn.com reports. “On Thursday, investigators did a trace of the handgun used in Wednesday’s shooting and determined that it was a .45-caliber handgun Roof purchased from a Charleston gun store in April, two law enforcement officials told CNN. His grandfather says Roof was given ‘birthday money’ and that the family didn’t know what he did with it.” Well now we know . . .

We also know Roof passed a Brady Bill background check. Which just goes to show that background checks are nothing more than feel-good security theater. In case you didn’t know already.
