"Without guns our world is safer", is a incorrect statement due to the fact that criminals will always have them. No matter how hard you try or what you do guns will always be out there, it's just like drugs people smuggle them in and no matter how hard we try they are still here destroying society. Now I don not believe we should have 50 guns in a school but if you want to stop shootings then you have to have armed personnel in the area at all times. Now that can be a law enforcement officer at every school or a school administrator who has gone through a training and passed a background check. The bottom line is that if you really want peace and you want the shootings to stop taking guns will not do a thing because in the end criminals have the guns and the law abiding citizens do not have them and will end in a tragedy every time.
