It's past time to admit the simple truth. Having armed, law-abiding citizens all around us will keep us all safer than about anything else we can do...and it is proven in the statistics and what has happened in the past at such incidents when they were there.
Thank you for that information Jeff! It may come in useful here at a town hall meeting if someone retorts that an armed citizen has “never” stopped a crazed gunman - those stories never get the same level of (if any) media attention.
