Legally registered guns are forbidden at most, but not all, public schools. These so-called “gun free zones” are hotly debated on both sides. Supporters of gun-free zones say they prevent gun violence because they prevent gun owners from accidently injuring themselves or their students. Additionally, they argue that well-meaning but untrained bystanders can accidently shoot the wrong person when trying to intervene during a shooting. On the other hand, opponents of gun-free school zones say that mass shooters will be undeterred by gun-free school zone policies and can only be stopped by armed bystanders. Most mass shootings, they say, have occurred in gun-free zones because the victims there are unable to defend themselves and stop the gunman. What do you think? Should public schools be gun-free zones?
