Diamondback Police Supply owner Douglas MacKinlay has halted Mark Kelly's attempted purchase of an AR-15 over concerns that Kelly was not in fact buying the gun for himself, and therefore could not have passed question 11a of the NICS background check form 4473.
Seems he didn't answer truthfully when filling out the form for the background check...
I get that, too . . . but the authorities did not give Mr. Kelley the money to buy the firearm.
