Thank you for your thoughtfulness to this important ministry. Yes, the Colonel once notified of an officer involved shooting, will send an autographed book to the involved officer or his/her agency. Most of the time the book(s) sent are a copy of “On Combat” or “On Spiritual Combat”. Our nation’s officers are fighting a spiritual battle in which the forces of good verses evil are pitted against one another. Thankfully, in the end, good will prevail! You can donate to this ministry online.

The Colonel can tailor his speaking times to the needs of the host. He has spoken for as little as 30 minutes up to 8 hours. It is best that he be given adequate time (90 minutes – 2 hours) to present. A full day can be split into several presentations.

Lt. Col. Grossman is well known in the military and law enforcement communities and often presents to these groups. He has been invited to the White House, church groups, fundraisers, and corporate events. He delivers important information to anyone who loves this country and their families.

Our former name served its purpose well for a time. Companies often change and innovate. Lt. Col. Grossman is a well-respected author and public speaker. He provides his readers and audiences with knowledge and truth. His books have a theme involving the word “ON” (On Killing, On Combat, On Spiritual Combat) and thus the new name seemed to fall in place—Grossman ON Truth.

KILLOLOGY, (n): The scholarly study of the destructive act, just as sexology is the scholarly study of the procreative act. In particular, killology focuses on the reactions of healthy people in killing circumstances (such as police and military in combat) and the factors that enable and restrain killing in combat and in our society.

According to Lt. Col. Dave Grossman, “The hard thing to explain is not that one-in-a-million horrible murder that you heard about today. The hard thing to explain is the 99.9% of our citizens who will go a lifetime and never even seriously attempt to take a human life. Think about it: divorce, infidelity, layoffs, traffic accidents; in a lifetime of provocation, less than one-in-a-thousand citizens will attempt to kill a fellow human being. Explain that!

“Criminology is not about teaching people to be criminals, and killology is not about teaching people to kill. The systematic process of understanding the variables that enable and restrain killing is essential to the survival of our civilization.”
