JEFFERSON CITY, Mo. (AP) — Several thousand online messages have piled up as Missouri Gov. Jay Nixon considers what to do with recently passed legislation that would bolster gun rights. Many of the messages urge Nixon to sign the legislation, calling them important protections of Missourians' rights. Some suggest he should veto the law, raising concerns about the potential ramifications. The Republican-led Legislature sent the Democratic governor several gun measures this year. One would declare void federal laws that infringe upon gun rights and would allow concealed weapons to be carried in school buildings by designated school personnel who complete training, have a valid permit and register with the Department of Public Safety. It also would lower the minimum age for obtaining a concealed gun permit from 21 to 19 and would make it a misdemeanor to publish identifying information about a gun owner. Another bill would bar the Revenue Department from keeping copies of documents needed for a concealed gun permit. A third measure would give county sheriffs responsibility for concealed weapon permits. Currently, sheriffs receive permit applications and issue paper permits that are taken to a local licensing office overseen by the Department of Revenue so that the person can receive a photo ID noting his or her permit. That legislation also would allow schools to teach a National Rifle Association-sponsored lesson or similar program to first graders about what to do if they find a gun. Gun legislation gained particular attention at the state Capitol this past year amid proposals in Washington for changes such as expanding background checks and prohibiting high-capacity magazines. Privacy rights for gun owners also attracted attention after legislators learned the Missouri State Highway Patrol had shared the list of people with concealed gun permits with a federal agent at the Social Security Administration. The Missouri governor's office has received messages about gun bills from people living in Missouri and elsewhere. The number urging Nixon to sign significantly outnumbered those urging him to veto, based upon a review of a sampling of the messages provided to The Associated Press. Nixon has until mid-July to sign, veto or allow the measures to take effect without his signature. Nixon spokesman Scott Holste said Friday the legislation still is under review. Gun Bill image
