Are the Gracie brothers qualified to opine?

It is understandable that law enforcement officers view Gracie Survival Tactics from various points of view.

Cynics and skeptics say

"I'm gonna guess these guys (Rener and Ryron Gracie) never wore a badge and only know what they see on the video."

"Monday morning quarterbacks....."

Perhaps the question to consider then "Are the Gracie brothers, specifically Rener and Ryron Gracie qualified to present and develop ground tactics specific for law enforcement?"

There isn't much debate on whether the Gracie family has a high level of expertise in Gracie Jiu Jitsu, especially since the family is attributed with the initial development of the art as well as having the greatest responsibility for the global reach.

How does Gracie Jiu Jitsu translate to current day Law Enforcement ground fighting and subject control?

GST has been taught to hundreds of law enforcement agencies (Local, State, and Federal), and the program continues to evolve every single day based on the feedback from those who put themselves in harm’s way every day and night.

As Rener Gracie likes to say “In the beginning, we were teaching jiu-jitsu TO law enforcement; now we’re teaching jiu-jitsu FOR law enforcement.”

An encounter between a law enforcement professional and suspect is vastly different from a street fight or a sport jiu-jitsu match. Yet, some defensive tactics programs make no distinction. GST is the fastest growing defensive tactics program in the world because it is the only “jiu-jitsu based” program that is 100% law enforcement applicable that has also been proven in actual combat by US military troops around the globe.
