These (the ones who banned the Veterans ceremony) are the same people who put up the blue fist signs, circulated recall petitions, and occupied the Capitol almost four years ago.
This isnt about irrational fears. This is about indoctrinating children to fear guns so as to make the possession and use of guns by anyone other than the government socially illegitimate.
The gun free school zone laws have always been about the indoctrination of children. They have never been about safety. School shooting have gone up since the law was passed.
