I got my LTCH because of stories like this, and all the times that I'm out and about with my wife and kids. My wife just payed her local fee Wednesday, so she'll be getting her LTCH soon and then there will be a gun in the glove box of our car at all times; I will still have one on my hip at all times and my wife will have one on her's.
This is definitely a great story and a great reason why every law abiding citizen should be armed and have the know how to stop a threat.
