Teachers want to teach they didn't sign up for target practice on kids/people who decide to come into the schools to shoot up other students/teachers.
It's a very sad world we live in these days and parents plus teachers should teach love, acceptance and tolerance for different cultures and skin colors. If we as adults would lead our children by example instead of all the hate they see these days life as we all know it could be so different.
The only teachers that should be armed are those that really want to be it should never be mandated for them to have to be.
Parents and teachers should pay more attention to the kids who are bullied, picked on, being abused at home, notice the ones that aren't quite right with possible mental issues and teachers make suggestions for them to get help and the parents should get them help.
No one needs an assault riffle unless you are military or police they should be banned and mandated to be turned in for the ones already out in the private sector.
I don't care if you want to go hunting or have a concealed weapon or have a gun in your home. But this killing of kids in schools needs to be stopped.
