Back in the arena of crime this week, Brazilian jiu-jitsu black belt Jennifer Gay sits down with Marnie to discuss predator psychology. They discuss the crime index for Oklahoma City, predators, the phases of an assault (from both strangers and non-strangers), and some psychological self-defense tools that you can take with you. Jennifer is an instructor at Redline Jiu-Jitsu Academy in Edmond, Oklahoma where she teaches self-defense to students of all ages.
