These idiot schools think, that banning squirt guns will prevent the usage of a real one.
And the narrow minded teachers think that "we are now doing something to prevent a problem".
They don't. The problem is at home. From the beginning of America people had guns at home, yet kids didn't take them to schools and didn't kill their classmates and teachers. It was not an issue until the second part of the 20th century. Thus, it has nothing to do with the guns. It is an upbringing issue, where kids today allowed to do whatever comes to their minds. Parents became robots who bring their kids up based on some hazy pink image of what should be right and wrong, which has little correlation to reality.

Actually in many cases they did take them to school. Either so they could hunt on the way to/from school, or to shoot at the school's gun range. They did not kill their classmates, teachers, staff, etc.
