There has been a lot of talk about preventing gun violence and finding ways stop “crazy people” from getting guns and shooting up theaters, malls, schools and churches. The problem with this is that none of the people who have committed mass murders are really crazy. A “crazy” person is a person who does not know what they are doing and does not understand the consequences of their actions. An example of a truly crazy person would be someone who is continually stabbing themselves with a pencil and not comprehending that this action is harming them. The people who commit mass-murders go to great lengths to plan and execute their actions. They are fully aware of what results their action will yield. These are people who are fully capable of hiding their intentions and blending into society. A mental check would fail to diagnose them as insane because they are not.
