Teachers often do a thankless job. Too often they get no respect from parents and they pay for supplies out of their own pocket. Yet many stats show a lot of money set aside for schools, yet where does it go? Not to teachers!
I don't know why we don't have only one entrance/exit into a school and have a security guard stationed there along with a metal detector. We have people scanned to go on airplanes and into government buildings - we should do the same for schools.
BTW, schools are already gun free zones, so we don't need to ban guns there since they are already banned. We need to make it easier to enforce this law.
