GABBY GIFFORDS' HUSBAND Mark Kelly buys an AR-15 'assault rifle'.

More here. What I find interesting about both reports is that Kelly saw a used one in the gun store, purchased it, did the background check, but still hasn't picked it up. Look, stores don't do the background checks until they have the cash in hand (even for an order), and if the AR-15 was in the store, he could have walked out with it. Why didn't he?

The most likely explanation is that the weapon wasn't in the store ... he ordered it.
