This is an absolutely surefire way to get attention. Unfortunately, the attention will come from the wrong places. After one of these "demonstrations" there would no doubt be a movement (possibly very successful) to outlaw firearms from ANY part of the Airport. If it is done at State Level, preemption will not be a problem.
Something in me says that the attention gained will be all wrong and will probably yield a "set back" rather than an "advancement" to the cause.
