I think the libs would love to have another TSA in the schools. Just think how many more schools there are than airports and how many democrat union votes that would produce.
What we need is a right to carry concealed by teachers and administrators and journalists who have the sense to not publish their names.
How far would the Sandy Hook shooter have gone if one or two faculty or staff had been armed? How about if there was an armed uniformed security guard who could have been the first target or avoided? Would he have attempted this at all if he thought there were an unknown number of people prepared to stop him?
Allowing armed staff is the only solution that is practical and will work but sorry to say it is not politically correct.
