DENVER (Reuters) - Owners and makers of assault-style weapons would face civil liability under a package of measures unveiled on Tuesday by top lawmakers in Colorado, a state shaken by some of the deadliest shootings in U.S. history.
The bills, introduced by Democrats who control the state legislature, could push Colorado to the forefront of a national gun control debate reignited by several mass shootings last year, including massacres of schoolchildren in Newtown, Connecticut, and moviegoers in suburban Denver.
Other states such as New York have moved to further restrict military-style assault weapons. But if the measures become law, Colorado would hold owners, manufacturers and distributors of firearms more accountable for gun violence.
Owners of semi-automatic rifles would be subject to strict liability for civil damages caused by their weapons, and state statutes that shield manufacturers, importers and dealers from such liability would be lifted.
Handguns, bolt-action rifles and shotguns would be exempt from the measure.
If passed it would put Colorado at odds with a 2005 federal law protecting gun manufacturers from being held liable for crimes committed with their products.
“Coloradans have asked us to lead on this issue, not to stand idly by while children are being gunned down in schools and movie theaters,” state Senate President John Morse said at a news conference in Denver.
The Democrats, who hold a majority in both houses of the Colorado Legislature, also urged passage of bills to ban sales of high-capacity ammunition magazines and to extend background checks for gun purchases.
A previous loophole that exempted firearms sales at gun shows from background checks was closed following the 1999 Columbine High School massacre in Littleton, where two students shot a teacher and 12 students to death before committing suicide.
Columbine stood as the deadliest U.S. public school shooting on record until 20 first-graders and six adults were slain by a gunman in December at the Sandy Hook Elementary School in Newtown, Connecticut.
Sandy Hook came five months after 12 people were killed and 58 were wounded by a gunman who opened fire during the midnight screening of a Batman film in the Denver suburb of Aurora.
Flanked by relatives of victims of the Columbine, Sandy Hook and Aurora shootings, Morse and House Speaker Mark Ferrandino also called for measures to prevent individuals under protective orders or convicted of domestic violence from possessing guns.
They further urged requiring concealed-carry permit holders to undergo in-person training.
Governor John Hickenlooper, a Democrat, has said he supports universal background checks and legislation to require that involuntary confinements of people with mental illnesses be reported more swiftly to databases used in screening potential gun buyers.
Both those measures were included in the package unveiled on Tuesday.
Beyond that, Hickenlooper “is open to a discussion about magazine limits and other ideas designed to keep guns out of the hands of dangerous people,” spokesman Eric Brown said.
Spokesmen for the majority leadership said it remained to be seen how many Democrats in the legislature would embrace the various measures in the package.
“Some will have unanimous support and some not so much,” said Dean Toda, a spokesman for the House majority.
Firearms ownership remains a politically touchy issue in Colorado despite its recent history of gun violence.
“These proposals cannot make Coloradans safer,” Senate Republican leader Bill Cadman said in a statement criticizing the Democratic leadership. “When only criminals have guns, more citizens will become victims.”
