Paul Markel just put up an article over on Officer.com reviewing a tactical course called “Red Zone”, taught by David Biggers. Here’s an excerpt:
“You are off-duty/plain clothes and armed, you pick the scenario: restaurant, shopping mall, church, etc. Johnny Jihad walks in and starts indiscriminately shooting up the place. This isn’t the square range with twenty foot dirt berms on three sides where there are nothing but you and a cardboard target. Our in the world there are more folks running around that should not be shot than those who should. If you are a copy you can’t just hide and call 9-1-1. Failure to act on your part would be a death sentence to innocent citizens or your family. Are you ready for the test?“
