LAX Shooter Passed NICS Background Check, Bought Gun Legally By Robert Farago on November 3, 2013 “A federal law enforcement official said that the Smith & Wesson assault rifle used in the attack is believed to have been purchased legally from a Los Angeles-area arms dealer,” usatoday.com reports. So . . . how’s that background check thing working out for you? Of course you know what this means: California legislators will redouble their efforts to pass an assault weapons ban. Because you can’t stop crazy people from buying the guns legally. (Go figure.) If Paul Ciancia modified the AR-15′s bullet button (ya think?) boom! Bullet button ban bill full speed ahead. Meanwhile, here at Bergstrom Airport there’s not a gun in sight at the security checkpoint. Sadly, not one concealed either (i.e. mine). Not that it’s all about me, but you know what I’m saying.
