North Carolina Democratic legislators and gun-control advocates want Republicans to allow debate and pass measures they say would keep weapons out of the hands of young people and those with mental illness. Speakers at a Legislative Building news conference on Thursday criticized GOP leaders for failing to act on their proposals years ago, well before recent mass shootings in Buffalo, New York; and Uvalde, Texas. Some proposals would require background checks for all gun sales, prohibit people under 21 from owning assault-style weapons and create legal process for so-called “red-flag” orders. Republicans are expected again to bottle up bills. Gun-rights advocates are influential at the General Assembly.
