As a teacher of 21 years, I have seen an alarming escalation of violent encounters in the US education system. It is a sad fact that it only takes one maladjusted person to paralyze an entire campus! Unfortunately, this is our reality now and it is our duty protect the innocent to our best ability. I believe Temp Shield can save our educators valuable time when they are gripped by an emergency and should be adopted by all schools across our country.
