I am a TEXAS school teacher... and, in my view, security guards are NOT the best solution. I'm hopeful that more Texas ISD's will create guidelines and training which will allow their TEXAS CHL teachers to carry while on duty. Teachers are charged with the safety and well being of school children eight hours a day, six months a year. Teachers carrying concealed does at least two things: 1) puts multiple guns on each campus; and, 2) deters the would be aggressor as a result of the possibility of multiple teachers and administrators being armed!
The math is simple: one or two security guards that are visible and easily targeted is less a deterrent than the chance of multiple teachers and administrators being armed with concealed weapons. The would be aggressor would not know which teachers and/or administrators were armed. I just feel that is a better solution. Plus, I don't like the idea of trusting the minimum wage security guard most ISD's will hire for the job to be capable of defending my life better than I will defend myself!
