Here at MDFI, we teach everything based on the whole person concept of a responsibly armed citizen. Mindset is the first and arguably the most important part about defending yourself and others. Having a proper mindset and understanding the mindset of those that would do us harm is crucial, and the expertise that Dr. William Aprill brings to the table is second to none. We are very proud to be able to bring him to the MDFI Alumni.

UNTHINKABLE: The Criminal Mindset

Unthinkable is, in brief, a tour of the dark side of our society: criminal violence. In one very full day, attendees will undertake a fast-paced and interactive overview of how Violent Criminal Actors think as they decide whom to victimize, focusing on our demeanor and behavior for cues that we appear easily victimized. Hands-on training will introduce robust, effective techniques for managing interactions with unknown contacts, who may or may not intend us harm, including disarming an assailant armed if necessary. The day will finish with an in-depth review of the psychological and social development of VCAs, with particular attention paid to incorporating this knowledge into a powerful, adaptive mindset of self-protection.

  • How do violent criminals think of us, and how do they target us?
  • How are human monsters made, and born?
  • What do we do when faced with unknown threats, even against a drawn gun?

All these questions recall threats that any reasonable person would avoid at any cost. So why would anyone pay to spend a day immersed in exploration of those threats and more? Simply put, there is no way to develop an effective and adaptive defensive mindset without spending time in some fairly dark places.

This course will explore the above domains and skill sets, guiding students to the next step in developing their ability to protect themselves and those they love. For participants in this course, a systematic approach to enhancing personal safety will be undertaken in an engaging and fast-paced format over a very full day of training.

Since defensive awareness is rooted in realization of risk, and since defensive preparation adds the commitment to mitigation of threats, unifying those elements in defensive decision-making will be the emphasis of this course.

It is the goal of the instructor to drag awareness of risk from the back of the mind to its very forefront, ensuring that an actual life-threatening scenario will not be the first time participants have honestly faced what will be necessary. Participants in this course will be presented with some challenging truths about the world as it is and asked to make serious, personal changes in how they pre-pare for that world.

Classroom components will include intensive, interactive lecture.
