Tim Larkin is an American self-defense expert, founder of Target Focus Training, and author of the New York Times bestselling book Surviving The Unthinkable.
Larkin's training is focused on teaching concepts and principles of manipulating the body to quickly and effectively induce injury in an asocial violent situation where an assailant is determined to cause harm or death to his victims.
[3] Larkin teaches his students to recognize when they can avoid violence, and when to use it if facing imminent, life-threatening danger.
[8] The book attempts to teach readers to identify the difference between social aggression (which can be avoided) and asocial violence (which is unavoidable), recognize personal behaviors that may jeopardize safety, and target highly specific areas on an attacker's body for a strategic counterattack.
[12] In May 2012, Larkin was banned from entering the United Kingdom by British interior minister Theresa May due to his methods of training.
