UPDATE:
A Texas School District has a policy allowing teachers to carry firearms.  Don’t mess with schools in Texas!

In the wake of 9/11 the United States Congress passed the Federal Flight Deck Officer program. Â It was a great idea: allow professional pilots already entrusted with enormous responsibility to carry firearms while at work so that in the event of absolute catastrophe they can be the last line of defense.
The brave volunteer pilots who participate in the program are trained and managed by the TSA.  Even though the program has been intentionally stalled by both the Bush and Obama Administrations, and burdened with ridiculous regulations (such as not allowing pilots to carry holstered firearms on their person), the program remains an excellent and free deterrent to air piracy/hijacking.
Ignoring for a minute the fact that municipal school boards in New Hampshire are political subdivisions that cannot tell their licensed employees that they cannot carry firearms, why not establish a voluntary FFDO-similar program available to all publicly employed teachers in our state?
The New Hampshire Police Standards and Training Council would be an ideal government agency for the General Court to task with assisting municipal school boards oversee training, compliance, and standards for public school teachers that wanted to participate.  This isn’t a suggestion to make teachers police officers.  This is a suggestion to make teachers able to protect themselves and others in the event of absolute catastrophe, just like in the air with the FFDO program.
It seems like common sense to me.
