There are three actions which would make school children far safer:

1. Access restrictions to schools so that armed men can’t just walk into a school: someone must let them in.
2. Add a compulsory Police check before a gun can be bought: mental health problems, a history of violent crime and/or threats of murder should exclude this person from buying a gun. they will just buy them illegally from gangs, but this will slow them down.
3. Third and most important: arm the school teachers, and allow them to return fire to protect their children. The current system of hiding or running is pathetic, and allows a coward with a gun to kill with impunity. Gun control is what we currently have on school grounds, and it is a complete failure. Arm the teachers; give the kids a chance!
