ACKNOWLEDGMENTS

Our gratitude to martial arts instructor Mauricio Machuca for sharing his experience of what it’s like to be on the wrong end of a knife encounter and to Federal Air Marshal M. Guthrie for providing insight into the effects of adrenaline on performance in combat. Thanks to Joey Kane, Chris Nunez, Adriana Tabile, Hazel Tabile, Natalia Tabile, and Raul Tabile for braving near arctic conditions to be stars in our photos. Also thanks to Sonia Lyris who not only starred in our pics but helped direct them as well. Much appreciated. Y’all rock!

For practical skills and applications, the list is long. Ron Bishop and Paul McRedmond for early training in ethically applying force: “You can do the right thing or the safe thing. We’re sworn to do the right thing.” Sensei Dave Sumner and Sensei Kris Wilder who taught new worlds of physical skills. Small Circle JJ instructor Stan Miller who taught stuff that made handcuffing much easier. Hundreds of officers, martial artists, and training partners, and thousands of crooks all of whom taught invaluable lessons. Thanks!
