There was a shooting today at Ohio State University - http://m.yahoo.com/w/ynews/article/topstories/1%3B_ylt=A0SO80Pog5ZL9CcASAIp89w4?url=http%3A%2F%2Fxml.news.yahoo.com%2Fus%2Fnews%2Frss%2Frichstoryrss.html%3Fu%3D%2Fap%2F20100309%2Fap_on_re_us%2Fus_triple_shooting_osu&.tsrc=yahoo&.intl=US&.lang=en - no doubt the campus is a "Gun Free Zone."
Not that either of the victims would have bothered with the means of defense if it wasn't; the point is that they were denied the choice.
Making areas "Gun Free" stands about as much of a chance at actually detering a gunman as making campus shootings with two guns illegal. Face it. It is nothing more than a fluffy pillow for the naïve heads of those with no sense of reallity.
