I received this message on Facebook: My name is Jamie Dunham, I was explaining to a friend tonight how your tactics saved my life a few years back (outside a gas station in Memphis). I just wanted to finally thank you, because if it weren't for my dad diligently training me with your technique, I am positive that my story would've come to a violent end five years ago. Thank you so so much. I am truly a living testament of your work. Her story is mind-blowing.
