It is time to repeal the Joe Biden "No Gun Safe Zone" law.
Teacher's don't have to carry or even touch a gun if they don't so desire. Those who wish to and can prove they have the skills and knowledge can if and when they want. Leave the potential shooter to wonder.
Do you really think taking down that sign is going to scare away potential mass killers? Most mass killers in schools either currently or previously attended the school. They are going to know if teachers are armed and if so, they will probably become the first target.
Gun free zones have little effect on mass killers but they have been very effective at reducing the number of guns being brought to school by students. Probably the biggest effect of tearing down the gun free zone signs is lots of kids will start bringing guns to school and that will certain lead to more dead and injured kids.
No, nothing will stop someone bent on causing multiple deaths. But putting up signs that say you are safe to come in here shooting because no one will have a gun to stop you sure hasn't done anything.
Do you think the sign saying it was a no gun zone kept any kids from bringing a gun to school if they were so inclined? Heck no.
The US has a far lower violent crime rate than many or all Western European Countries because the criminal just doesn't know if kicking in my front door is going to be met with a pump shotgun. It works in our home, what is the harm in making the shooter guess?
