Wyoming Says O.K. to armed teachers. :: 02/19/2014

While some have pointed to tragedies such as that of Sandy Hook and Aurora as reasons to disarm the populace, others recognize those moments as further reason to honor the Second Amendment. That is why lawmakers in the Wyoming Legislature voted 54 to 6 on February 13 to advance a bill that would permit individual school districts "to allow teachers and other school workers" with concealed carry permits to bring their guns on campus.

THIS is the "reasonable gun law" that we're looking for.
