HARTFORD, Conn. The state Senate on Wednesday approved wide-ranging legislation in response to last year's deadly school shooting in Newtown, including gun control measures that ban the sale of large-capacity ammunition magazines and 100 weapons that previously had been legal.
Following a respectful and at times somber debate, the Senate voted 26-10 in favor of the bill crafted by leaders from both major parties in the Democratic-controlled legislature.
The bill was to go to the House of Representatives, which was expected to pass it. It would then be sent to Democratic Gov. Dannel P. Malloy, who has said he'll sign it.
The December massacre of 26 people inside Sandy Hook Elementary School, which reignited a national debate on gun control, set the stage for changes in Connecticut that may have been impossible elsewhere: The governor, who personally informed parents that their children had been killed that day, championed the cause, and legislative leaders, keenly aware of the attention on the state, struck a bipartisan agreement they want to serve as a national model.
"The tragedy in Newtown demands a powerful response, demands a response that transcends politics," said Senate President Donald E. Williams Jr., a Democrat. "It is the strongest and most comprehensive bill in the country."
The legislation adds more than 100 firearms to the state's assault weapons ban and creates what officials have called the nation's first dangerous weapon offender registry as well as eligibility rules for buying ammunition. Some parts of the bill will take effect immediately, including background checks for all firearms sales
Connecticut will join states including California, New York, New Jersey and Massachusetts in having the country's strongest gun control laws, said Brian Malte, director of mobilization for the Brady Campaign to Prevent Gun Violence in Washington.
"This would put Connecticut right at the top or near the top of the state with the strongest gun laws," Malte said.
Colorado and New York also passed new gun-control requirements in the wake of the Newtown shooting, in which a 20-year-old gunman used a military-style, semi-automatic rifle to kill 20 first-grade children and six educators.
Compared with Connecticut's legislation, which, for example, bans the sale or purchase of ammunition magazines holding more than 10 rounds, New York restricted magazines to seven bullets and gave owners of higher-capacity magazines a year to sell them elsewhere. Colorado banned ammunition magazines that hold more than 15 rounds.
"There are pieces that are stronger in other states, but in totality, this will be the strongest gun legislation passed in the United States," Betty Gallo, a lobbyist for Connecticut Against Gun Violence, said of the Connecticut bill.
"CBS Evening News" anchor Scott Pelley spoke to the families of the victims of the Newtown shooting about the legislature limiting the size of the magazines to 10 rounds for an upcoming piece on "60 Minutes". It prompted a response from Nichole Hockley, the mother of Dylan, who was killed in the shooting. "Had he [gunman Adam Lanza] had, you know, 30 magazines instead of the ten, that's a lot of weight to carry. So he might have not brought as much ammunition into the school in the first place. ... He left the smaller capacity magazines at home, that was a choice the shooter made. He knew that the larger capacity magazine clips were more lethal."
The legislation was unveiled this week, and debate began Wednesday in the Senate.
Many senators spoke of balancing the rights of gun owners with addressing the horror of the Sandy Hook shooting. Lawmakers said they received thousands of emails and phone calls urging them to vote either for or against the bill, with veteran Sen. Joan Hartley, a Democrat, saying she's never seen a more polarizing issue at the state Capitol.
Gun rights advocates who greatly outnumbered gun-control supporters in demonstrations at the Capitol railed against the proposals as misguided and unconstitutional, occasionally chanting "No! No! No!" and "Read the bill!"
"We want them to write laws that are sensible," said Ron Pariseau, 66, of Pomfret, who was angry he'll be made a felon if he doesn't register his weapons that will no longer be sold in Connecticut. "What they're proposing will not stop anything."
In the legislature, where Democrats control both houses, leaders waited to unveil gun legislation until they struck a bipartisan deal that they say shows how the parties can work together elsewhere. They touted the package as a comprehensive response to Newtown that also addresses mental health and school security measures, including $15 million to help pay for school security infrastructure upgrades.
But momentum on federal legislation has stalled in Congress, and President Barack Obama has planned a trip to Connecticut on Monday to step up pressure to pass a bill.
A silent majority in favor of stronger gun control has emerged following the Newtown massacre, Gallo said.
Among gun control advocates are Dan and Lauren Garrett, of Hamden, wearing green shirts in honor of the Sandy Hook victims, who traveled to Hartford with their 10-month-old son, Robert, to watch the bill's passage.
Both hope lawmakers will build on the proposal.
"It's just the beginning of this bill. In six months from now, it's going to get stronger and stronger," said Dan Garrett. "I think they're watching us all over the country."
But gun rights advocates and some lawmakers questioned whether the legislation would have done anything to stop Adam Lanza, who blasted his way into Sandy Hook Elementary. State police say he fired 154 shots with a Bushmaster .223-caliber rifle inside the school, then killed himself with a handgun. He had also shot to death his mother, Nancy, before going to the school, and search warrants of the Lanzas' home showed it was packed with weapons and ammunition.
In a state where gun manufacturing dates back to the Revolutionary War, law-abiding gun owners are paying the price for the actions of a deranged young man, said a Republican state senator, Tony Guglielmo.
"The problem is I can't connect the dots between Adam Lanza and the good guys. So I think we need to do something, but I guess we should be doing something that does good, not something that just feels good," he said.
In his interview with the Newtown families, Pelley asked them if they fear that after only four months, the memory of how they felt on that day is beginning to fade. "Four months? It feels like it just happened a moment ago," said Francine Wheeler, who lost her son Ben. "And yet -- and yet, it's been years since I've seen my son. Okay? So whether it's, you know, become less on the American mind right now, it will -- it will come back, because we are here, and we're not going."
