Many legislators spoke of balancing the rights of gun owners with addressing the horror of the Sandy Hook shooting. They've received thousands of emails and phone calls urging them to vote 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.
But Senate Minority Leader John McKinney, R-Fairfield, whose district includes Newtown, said he felt he was representing the interests of the Sandy Hook victims as he cast his vote.
"I stand here as their voice, as their elected representative," he said, reciting the names of the 26 victims at the school.
Lawmakers appeared to still be stunned by the enormity of the massacre.
"When a child is sent to school, their parents expect them to be safe. The Sandy Hook shooting rampage was a parent's, a school system's, a community's and the nation's worst nightmare," said Republican state Sen. Toni Boucher of Wilton.
Gun rights advocates who greatly outnumbered gun control supporters in demonstrations held earlier in the day 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, 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."
By the time the Senate voted around 6:30 p.m., many of the gun rights advocates had gone home, leaving behind proponents of the bill who applauded when the tally in the Senate was read. The halls were mostly empty by the time the House voted at 2:26 a.m. on Thurdsay.
House Minority Leader Lawrence Cafero Jr., R-Norwalk, who helped craft the bill, said he realizes the gun owners are unhappy with the bill, but he stressed that no one will lose their legally owned guns or magazines under the legislation.
"We did our job. We did it together," he said. "We did the best we could and I think we did a good thing."
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 the creation of a new council to establish school safety standards and the expansion of circumstances when someone's mental history disqualifies him or her from obtaining a gun permit or other gun credentials.
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 the gun control advocates were Dan and Lauren Garrett, of Hamden, wearing green shirts in honor of the Sandy Hook victims. The Garretts traveled to Hartford with their 10-month-old son, Robert, to watch the bill's passage. They said they 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," Dan Garrett said. "I think they're watching us all over the country."
