Hmm... Mark Kelly bought an AR-15 and high cap magazines
Here in Tucson, just a day after testifying against them in Colorado. He must live on this (eastern) end of town... the dealer where he bought it is not far away.
He also picked up a 1911. Our tastes are similar -- admit it, Mark, you want this sort of stuff!
UPDATE: I don't see his statement as "I bought the rifle so I could turn it over to police," but as "I bought the rifle, and seeing as it's become an issue, I'll turn it over to the police, drat!"
