TUCSON, Ariz. (AP) — Two dueling gun events played out in the hometown of former U.S. Rep. Gabrielle Giffords on the second anniversary of her shooting, illustrating the sharp divide between gun reform advocates and Second Amendment stalwarts.

Tucson City Councilman Steve Kozachik staged a gun buyback Tuesday in the parking lot of the Police Department, offering $50 grocery store gift cards to anyone who surrendered firearms to be destroyed.

Just a few hundred feet away, GOP state Sen. Frank Antenori held an event where a dozen people offered cash for guns to be added to their own collections.
