The national news is full of reports showing how many are killed each year by fools and bad guys with guns. Each month I receive several pro gun magazines that report about 10 incidents each where the presence of a firearm saved lives. In many of these reports no shots were fired. Here is one incident of a good woman with a gun that should be front page news. It makes it very clear why armed citizens are the very best 1st responders
Good men and woman with guns who stop bad people from preventing mass shootings prevent mass shootings… therefore there is no mass shooting to report.
The only reasonable way to stop a bad person with a gun is to have a good person with a gun.
