The United States of America is number one in the world for many reasons. The United States has the most top ten universities of any country (Bridgestock), the most medals won at the Olympics since they began, the most powerful military (Johnson), the five largest corporations, and fourteen brands among the most valuable in the world (Wile ), but the United States also ranks first in one of the most unacceptable categories. The United States is the country with the highest number of school massacres in the world. The school massacres are clear and pose a danger to every campus in the nation. The worst school massacre in the United States didn't involve shootings, it was a bombing that killed over forty people. While school homicides only account for less than 1% of all homicides and suicides among teenagers. During my first semester of college I learned something very important in one of my political science classes. During a debate about allowing stowaways on campuses, I learned that the average police response time is over nine minutes. The massacre will be over before the police even arrive on the scene. A greater number of school massacres end due to a shootout with the police or the suicide of the mutilator. In both cases the killing of innocent civilians ends before the police arrive and have time to react to the situation. Some attempts to exterminate the inhabitants of a school have been known to occur simply because the killer has developed an appetite for masculinity or power and control over people. Allowing concealed weapons is the right solution because the idea that people can defend themselves can deter a killer. A power-addicted psychopath will not feel very powerful or in control if there is a possibility of being on the receiving end of some guns, which students of the past would not have brandished, when he or she is attempting to commit an act. of terrorism. Allowing the concealed carry of weapons can take away the irrational butcher's perceived power before he or she decides to act. Rationality can be restored before lives are taken and psychiatric care could possibly be provided to the tormented soul. There is no guarantee that this will stop every disturbed person from relentlessly pursuing the fear of helpless humans. The only way to stop someone like this from killing is to disarm him before he can manage to kill anyone in sight. A person with a concealed weapon may be able to resolve the situation before there are casualties
