TUCSON, Ariz. -- Tuesday was not just a day for Tucson to remember the victims of the deadly shooting that severely injured then-Rep. Gabrielle Giffords. It was also a day when residents could see firsthand the nation's gun debate play out in a busy parking lot outside a city police station.
On one side was a councilman who supports gun control leading an effort to give $50 grocery store gift cards to anyone who turned in their guns to police. And on the other was an event organized by a state senator that turned into an open, unregulated and legal marketplace for firearms.
"We have a fundamental hole in the private sales of guns. You can walk up right in front of a cop and buy a gun, no background check, nothing," said Councilman Steve Kozachik. "How much more flawed can the system be?"
The people who bought guns from each other declined repeated requests for comments.
The dueling gun buy-back programs -- and the annual ringing of bells to remember the six dead and 13 injured, including Giffords -- came as the congresswoman and her husband announced that they were forming a political action committee aimed at curbing gun violence.
Giffords and husband Mark Kelly, a former astronaut, wrote in an op-ed published in USA Today that their Americans for Responsible Solutions initiative would help raise money to support greater gun control efforts and take on the powerful gun lobby.
"Achieving reforms to reduce gun violence and prevent mass shootings will mean matching gun lobbyists in their reach and resources," the couple wrote. They said that it will "raise funds necessary to balance the influence of the gun lobby."
There was already some concern among gun control advocates that they were losing the momentum they hoped to have after the Newtown, Conn., elementary school shooting that left 20 children and six adults dead. Congress was already occupied with budget concerns.
Giffords' announcement brought back memories from the 1980s when Jim and Sarah Brady formed the Brady Center to Prevent Gun Violence. Brady, then-President Ronald Reagan's press secretary, was wounded in the 1981 presidential assassination attempt by a mentally ill gunman.
Brady's organization has been among the most vocal champions of gun control since then, but it remains to be seen whether Giffords' group can better compete against the National Rifle Association and its huge fundraising and political clout.
The NRA spent at least $24 million in the 2012 election cycle, including $16.8 million through its political action committee and $7.5 million through its affiliated Institute for Legislative Action. By comparison, the Brady Campaign spent around $5,800.
And when it comes to direct lobbying of lawmakers, the NRA was also dominant. Through July 1, the NRA spent $4.4 million to lobby Congress, compared with the Brady Campaign's $60,000.
"This country is known for using its determination and ingenuity to solve problems, big and small. Wise policy has conquered disease, protected us from dangerous products and substances, and made transportation safer," the couple wrote.
"But when it comes to protecting our communities from gun violence, we're not even trying -- and for the worst of reasons," they said.
As a House member, Giffords was a centrist Democrat who represented much of liberal-leaning Tucson but also more conservative, rural areas. She supported gun rights and said she owned a Glock pistol. In the editorial, the couple said they own two guns that are locked in a safe at their house.
They hope to raise funds for political activity, so "legislators will no longer have reason to fear the gun lobby."
The couple was expected to discuss the initiative in an interview airing Tuesday on ABC News.
The network offered a preview of the interview Monday and during "Good Morning America" on Tuesday. Kelly described a meeting with a father of a Connecticut victim in which he "just about lost it" after the parent showed him a picture of his child.
When asked by Diane Sawyer about when such violence happens to school children, Giffords responded: "Enough."
Newtown Selectman Jim Gaston, who was among the officials who met with Giffords and her husband last Friday when they visited, said he many others in town are behind her efforts. "I think she'll find support from the vast majority of my fellow Newtowners," Gaston said.
Gaston said he has a couple rifles himself and has always enjoyed shooting, but there is no reason for civilians to have semiautomatic weapons.
An attorney who lives in the Sandy Hook section of Newtown, Monte Frank, is organizing a bicycle ride from Sandy Hook to Washington, perhaps in March, to call for stronger gun control laws. He said he is eager to help Giffords anyway he can.
"It's been two years now that she was shot and people were killed. I would have thought that Congress would have done something when one of their own was the victim of unnecessary gun violence," Frank said.
In Tucson, residents rang bells at 10:11 a.m. -- the moment a mentally ill man using a handgun with an extended magazine opened fire on Giffords as she met with constituents in 2011 outside a Safeway supermarket. Mayor Jonathan Rothschild rang a bell at a fire station 19 times -- one for each victim.
At the gun events, Kozachik, the councilman, said that as the Tucson shooting fades from the public's mind, issues like controlling the sale of large-capacity magazines and keeping guns from the mentally ill need attention.
"This gave us the opportunity to keep the conversation going on a very sensitive day in this community," he said.
About 200 firearms, many of them old, some inoperable, were turned in during the event, police said. They were set to be destroyed later in the day. Kozachik said he handed out about $10,000 worth of gift cards from the grocery store chain Safeway.
In response to the event, Republican state Sen. Frank Antenori, who did not win re-election in November, organized a gathering outside the same police station where about a dozen people offered cash for guns.
Antenori and Kozachik accused each other of acting out of political motivations. Antenori said the councilman was sullying both the Tucson and Connecticut school shooting victims by the timing of the buy-back. Kozachik said the legislator was just trying to keep his name in the news and remain relevant.
The senator didn't stick around, while Kozachik stayed until the event ended at noon. Kozachik said the cash-for-guns scheme only served to bolster his argument that firearms laws need to be enhanced.
At his event, police documented each gun, took down names of those dropping them off and checked to be sure they were legal before loading them into a truck for destruction. A few hundred feet away, men holding signs reading "Cash for Guns" bought rifles and handguns. No paperwork, no questions asked.
Tom Ditsch, who stood watching both events, said neither accomplished anything. "Every gun that came in was an old gun, no assault weapons," he said with disgust. "They didn't even take any weapons off the streets that they wanted to."
