I am former military, former law enforcement, and a lifelong firearm owner. I am the worlds biggest fan of private ownership of firearms (with exception of convicted felons, those addicted to drugs, etc etc etc), and CCW's by those who can pass whatever is required by their local laws. In many cases (McD's, Post Offices, etc) where shootings have happened in the past, I feel that a firearm in the hands of one good guy could have made all the difference in the world. But in the jurisdictions I am familiar with, firearms are not allowed on school grounds by any other than peace officers. One may have a CCW, but it does not allow carry on a campus, so it is a moot point in this case...
