Glad to hear your friend came out of this on top and that I'm also glad the story made the news. These events happen weekly, if not nearly every day, and need more press. As little as I use Facebook, I re-post articles like this and they always strike conversation.
Contrary to those with wild imaginations and dreams of controlling everybody's minute-to-minute actions, there was no shootout, there was no wild spray-and-pray from a semi-automatic (autoloading!!!!) concealable handgun. There were no stray bullets, no bystanders were killed, no children or kittens were scarred for life. One well-placed, controlled round drastically changed the outcome of the situation.
Can you inquire as to what type of ammunition he had loaded?
