I cannot understand the insistence on banning guns from school campuses. It seems that some people have the peculiar idea that the behavior of psychotics and criminals can be controlled by the issuance of statutes. Criminals are criminals, by definition, because they disobey laws. Does it make any sense to expect them to obey a gun ban? Psychotics that shoot everyone in sight have no concern for law or punishment; they are basically suicidal and intend to expire with their victims.
Laws, on the other hand, are highly effective on stable and well-adjusted people. This group, which could provide protection against the criminal and crazy elements, are very effectively disarmed. Thus, the gun bans arm the criminals and disarm their victims. In addition, these laws inform the perpetrators that they will have nothing to fear from the people they attack.
In the entire sorrowful history of mass shootings, there has never been a single instance of a legally owned gun being involved.
If there is any detectable sanity in such a system, I would love to have it explained to me.
