An impromptu gun buyer sells a gun to a woman that he purchased outside a police station in Tucson, Ariz. Tuesday, Jan 8, 2013. About a dozen buyers offered cash to sellers in the parking lot of a police station where Tucson City Councilman Steve Kozachik set up a gun buy back program asking people to turn in their guns for a $50 gift certificate to a grocery store. The buyers were trying to purchase weapons from sellers in an effort to circumvent Councilman Kozachik's buyback program. (AP Photo/Matt York)
