Louisiana's constitution flatly says the right to bear arms shall not be abridged. But it also contains a clause that allows legislators to pass laws that bar people from carrying concealed weapons. Voters will be asked whether they want to tinker with that language on Nov. 6. The second item on a list of proposed constitutional amendments would strike the exception and add language designed to strengthen already strong gun possession rights in the state. Backers say it will give Louisiana the strongest gun protection in the nation, while opponents say it could negate prohibitions of concealed handguns on college campuses, in churches, and in government buildings and gun-free zones around schools. The amendment is one of nine proposed constitutional changes that will be on the Nov. 6 ballot.
