A Republican lawmaker is renewing his effort to allow concealed carry permit holders to carry guns into some public buildings.

Saying signs don't protect people from “homicidal maniacs,'' the state Senate voted 18-12 on Thursday to allow people with concealed-carry permits to bring them into unsecured public buildings.

It doesn't look like Arizonans are going to be able to bring their guns in to public buildings.

Calling it a right of self-defense, a Senate panel voted late Tuesday to give the go-ahead for hundreds of thousands of Arizonans to bring their guns into public buildings.

For the second year in a row, Gov. Jan Brewer vetoed a bill that would have allowed people to carry guns in government buildings. HB2729 would have required any government entity in Arizona to allow firearms in public buildings, unless the buildings had adequate security measures to ensure that no one could bring a gun inside.

A bill that would allow people to carry guns into public buildings where they're currently banned has met final approval by the Arizona Senate.
