NATIONAL NEWS (CNN) — A bipartisan legislative task force in Connecticut has agreed on a major overhaul of the state's gun laws in the aftermath of December's deadly attack on an elementary school, lawmakers announced Monday.
The draft legislation would add more than 100 types of guns to the state's list of banned assault weapons; limit the capacity of ammunition magazines to 10 rounds; ban armor-piercing bullets; require background checks for all weapon sales, including at gun shows; establish safety standards for school buildings; allow mental health training for teachers; and expand mental health research in the state.
"Nobody will be able to say that this bill is absolutely perfect, but no one will also be able to say that this bill fails the test when it comes to being the strongest in the country and the most comprehensive bill in the country," Connecticut Senate President Don Williams, a Democrat and a member of the task force, said Monday.
The General Assembly will take up the legislation when it returns to session Wednesday.
"There is nothing in this package that would have stopped someone like Adam Lanza," said Scott Wilson, president of the Connecticut Citizens Defense League, referring to the gunman who killed 26 children and adults December 14 in Newtown, Connecticut. "In his case, he stole the guns and went on a murderous rampage.
"Limiting magazine capacity or mandating registration will only affect law-abiding persons, not criminals bent on murder," Wilson added.
A Republican member of the task force, House Minority Leader Larry Cafero, tried to reassure gun owners.
"No gun owner will lose their gun, no gun owner will lose their magazine, they will not lose the use of said gun or magazine, so long as they follow our rules and register," he said. "Are there tighter restrictions on their use, etc.? Absolutely. We also were able to see as part of this legislation the repeal of early release for violent criminals."
The bill would expand the definition of an assault weapon by reducing to just one the number of specified "physical characteristics" that need to be present. Current law requires two.
The legislation would immediately ban any further sale, purchase or importation of magazines that can hold more than 10 rounds, but would allow current owners of larger-capacity magazines to keep them.
However, those magazines would have to be registered with the state by January 1, and even legally registered magazines could not be loaded with more than 10 rounds outside of the owner's home or a gun range, no matter what permits the gun owner may hold.
"It is ludicrous to expect people that have firearms capable of holding 15 rounds to only load 10 rounds inside of them," Wilson objected. "Do criminals really care about these laws?"
Families of the children slain in Newtown were disappointed the larger-capacity magazines were grandfathered in. They asked Monday for an across-the-board ban.
"On behalf of the loved ones who were violently taken from us, please reconsider your approach to large- capacity magazines as part of the comprehensive package of gun legislation," the families wrote in a letter to lawmakers.
Gov. Dannel Malloy backed the families in a statement Monday.
"They've asked for an up or down vote on that provision," he said, "and, whether it's in the larger bill or as an amendment, the families, and every resident of our state, deserve a vote.
"I have been clear for weeks that a ban on the possession and sale of high-capacity magazines is an important part of our effort to prevent gun violence," he added. "Simply banning their sale moving forward would not be an effective solution."
In addition, the bill would create the nation's first statewide registry for people convicted of crimes involving the use or threat of dangerous weapons. The registry would not be public, but available to law enforcement only. Furthermore, it would require eligibility certificates for the purchase of any rifle, shotgun or ammunition, and would significantly increase penalties for illegal possession and firearms trafficking.
Other parts of the bill establish safety standards for school building projects and require each school in the state to develop a safety and security plan. It also requires safe school climate committees to investigate instances of bullying and other threatening behavior. Other provisions address security at colleges and universities.
The bill allows school districts to require "mental health first aid" training for school personnel and creates a task force to examine the state's mental health system. Additionally, it alters state insurance regulations to beef up mental health care coverage.
Williams, the Senate president, told CNN he expected strong support for the bill from both sides of the aisle because of the bipartisan task force that put it together.
"We have broken the gridlock on the most controversial issue," he said in announcing the agreement.
"Democrats and Republicans were able to come to an agreement on a strong, comprehensive bill," he added. "That is a message that should resound in 49 other states, and in Washington, D.C.. and the message is we can get it done here and they should get it done in their respective states and nationally in Congress."
The task force is made up of Williams and fellow Democrats House Speaker Brendan Sharkey, Senate Majority Leader Martin Looney and House Majority Leader Joe Aresimowicz; along with Senate Republican Leader John McKinney and Cafero, the House Republican leader. It based the draft legislation on proposals created by 16-member bicameral working groups on the topics of gun violence, school security and mental health.
"It's important for us to act quickly, but it's more important for us to act intelligently," Sharkey said. "It's also critical that we send the message to Washington and to the rest of this country that this is the way to get this job done. To do it in an effective, meaningful, thoughtful way and to do it in a meaningful, bipartisan basis, because our children deserve no less."
