Meet the Colonel!

I met Lt. Col. Grossman (US Army - Retired) at a class in South Georgia over a decade ago. We were both students in a shooting / fighting transition class. He signed his book for me and wrote a nice personal note.

As a former Marine, I heard him speak several times. Col. Grossman regularly speaks with troops headed to combat. He has authored almost two dozen published books, most famously On Combat and On Killing.

Lt. Col. Grossman speaks in depth on the issue of sleep in the law enforcement and military communities, and the lasting effects that come with it.

Thank you, sir, for coming on - it was my honor to speak with you (and Charlie, of course) and help you spread the good word.

Happy Friday!

During the interview released Tuesday, January 6, 2026, Robert went into a general overview of use of deadly force investigations.

During this interview we will go further into the topic.

The knowledge you take away from these two episodes could save your career, freedom and financial security. Read and understand the case law linked in the previous description.

And once again and most importantly - bring this to someone you trust to test us. The salty old Sergeant that has been puttering around since the '80s and did some years on SWAT. The lieutenant that had three shootings as a young patrolman. Ask them if they were mentally prepared for what followed the incident and if our discussion is accurate regarding the factors to determine legality and what follows the shooting.

Not only will building your knowledge base protect you post-shooting, it will allow you to act more decisively at the time of the gunfight. It will help you prepare for the operation that leads to the incident.

Know the law, know the policy, succeed.

Between homicide investigations, homicide supervision and state level investigations, Robert has spent considerable years collecting facts following violent crimes. If you wear a badge and carry a gun, there is a chance that at some point you will pull the trigger while aiming at a human.

Doing this without a justifiable reason is a crime - aggravated assault, attempted murder, murder.

Doing this within law and policy is deemed "justified" - kind of like that bad TV show where the cop in the cowboy hat shoots someone every episode and then says, "It's justified."

Having investigated many officer-involved deadly force encounters, Robert is highly qualified to discuss the legal standards involved in his investigations, case law, and generally what to expect in the hours and days following your incident.

After you pull the trigger is not the time to find out if you have to give a statement immediately, timing of report writing, and generally what the investigators will be looking at.

No surprises needed on the most traumatic and pivotal day of your career.

As always, you are encouraged to listen with a critical ear. If someone you work with has had one or multiple officer-involved shootings, encourage them to listen and confirm accuracy.

In the first of several interviews with CIA Paramilitary Operations Officer (OO) and Marine / Silver Star recipient Adam Sikes, Adam will introduce himself and delve lightly into his background.

We all know the Central Intelligence Agency is a thing and that they tinker in the global intel realm. We've seen some TV shows, movies, and maybe read a book.

Adam will provide insight to what they actually do from firsthand experience.

This will be the first of several episodes, so stay tuned and enjoy!

Let's continue to analyze the best practices to safely take structures as LEOs. Christmas being in two days does not reduce the danger of this job. Continue to develop in order to go home safe.

When civilians watch videos of building clearing, they see the physical movement. They largely analyze with an untrained eye. They base their opinion on the result.

As LEOs, our goal is enhancement of the process. Out-think, out-maneuver, out-train the opposition.

Thank you for listening and for continuing in your own self-development. If you are deep in the holiday season and continuing down the road of reflection and growth, you are in the top 5%.

Keep it up, stay safe, stay warm, but stay frosty.

If you carry a gun to work - police & military, I'm looking at you - you've been trained in CQB. Were you trained well? Perhaps. Were you trained badly?

I have been.

Although CQB is subjective, we can learn from the mistakes and blood of others. We don't have to get blood on our own hands due to poor (or lack of) tactics.

Unfortunately, most established units that have a way of doing things will not change until they see the failure themselves.

I'm passionate about CQB. I've done an episode on complacency because I've seen it, and it's overwhelmingly visible in some CQB situations.

Let's get thinking about our tactics. Are the tactics we're using just good in training, or will they work on the two-way range? Are we training in a way that encourages target identification and reactions? Are we building training scars?

The answer is yes, we are developing training scars.

All training will come with some level of scarring, and we have to constantly adjust.

Become conscious of what you're doing, and be humble enough to learn from someone doing it better and personally evolve.

Stay smart, think fast, stay alive and keep your friends alive through a change of CQB mindset!

Knowing the streets can make or break a case.

The 1960s are gone where cops just run around with a 4-cell mag lite flashlight and thump folks. We're a quarter way through the 21st century, so let's learn to communicate with our lovely communities. That may mean knowing what people are talking about when they say the following phrases:

That hoe slaps!

That junt fye!

12 got my stolo!

Bows on deck for the low!

Got the drop on the opps! Lets slide

If you are in law enforcement and can't speak street slang, expect to be a step behind. Imagine dumping a phone as a detective into Cellebrite or looking through one as a patrol officer on the street and reading some of these, and not knowing that message five is about killing rival gang members, or message four is about selling pounds of drugs.

Although slang varies from place to place, I've worked wiretaps involving criminals from all over the country and there is significant overlap. Learn this slang from me, but more importantly, open your ears and mind to learning the slang in your area.
