TOPEKA — Gov. Sam Brownback on Friday announced the signing of several bills into law, including one requiring public schools to make their facilities available to supervised air rifle clubs in the same manner they accommodate other clubs and activities.

House Bill 2502 also makes changes to the state’s concealed carry laws, prohibiting public employers, including cities and counties, from banning their employees from carrying concealed weapons when they are working outside of a public building.

The BB gun bill was prompted by a controversy in the Derby school district where a BB gun club had been meeting in one of its buildings since 1985.

But last year, the school board voted by a narrow margin to change its policy, citing the Kansas Weapons Free Schools Act, which requires districts to adopt policies prohibiting firearms in schools and to expel any student who violates the policy.

In the final days of the 2016 session, a conference committee combined it with other bills making changes to the state’s concealed carry laws.

Among those is a provision that guarantees public employees such as code enforcement officers, meter readers and other crews who work outside of a public building are allowed to lawfully carry concealed handguns on the job.

Another provision, however, makes it easier for city and county commissions and other public boards to ban weapons from their meetings by allowing them to set up temporary checkpoints at the entrance of their meeting rooms on meeting days.

Otherwise, all public buildings except school buildings soon will be generally open to concealed carry unless the local government in charge of the building has adequate security to prevent anyone from bringing in weapons. That law goes fully into effect next year.

Another provision of the bill allows Kansas residents who are on active military duty outside the state to apply for a Kansas concealed carry license. Kansas no longer requires such a license, but such licenses do enable Kansans to carry weapons in other states that do require them.

Other bills Brownback signed include:

• House Bill 2632, revising provisions of the Sales Tax and Revenue, or STAR bond financing law.

• House Bill 2696, providing additional funding for the Kansas Highway Patrol Staffing and Training Fund and Law Enforcement Training Center.

• Senate Bill 323, creating the Jason Flatt Act requiring suicide prevention training for school district personnel.

• House Bill 2056, allowing the Attorney General to oversee the licensure of bail enforcement agents, also known as bounty hunters.

Brownback has now signed 89 bills into law this session and vetoed two.
