Reference: Links where CHLs have stopped past mass shootings I just thought it might be handy to create a thread where we can posts links to news stories of armed citizens intervening to stop mass shootings (or perhaps the Killeen case where prohibition by law prevented an intervention) 1. Luby's Killeen - Suzanna Gratia Hupp had a handgun; but had left it in the glovebox of her car in order to obey state laws prohibiting the carry of concealed weapons at the time. Both her parents were killed and this tragedy led to a change in the law. 2. Pearl, MI - High school principal stops school shooting with a .45 Anybody else have more?
