SIOUX FALLS - South Dakota is the only state that so far has passed a law allowing school personnel to carry guns in schools, despite the proliferation of such bills in the aftermath of the Newtown, Conn., massacre.

The South Dakota Legislature earlier this year approved a law that would let trained officials carry guns in public schools, so long as the district approves it. It's unclear yet if any schools plan to have armed staffers come next school year.

Kansas is poised to pass a similar proposal. Arkansas has enacted a law allowing colleges to let staff with concealed gun permits bring their weapons on campus.

But even traditionally gun-friendly states have faced opposition from educators and reluctance from some governors.

Twenty-six children and staff were killed Dec. 14 in Newtown.
