Arrestling?

Does anyone have experience with this system? How does it compare to or differ from some of the other defensive tactics systems for LEOs, such as ISR Matrix or the Gracie, Blauer or Dogbrothers "Die Less Often" material?

Have not experienced it first hand but the video clips I have seen showed people wearing gunbelts over their gi and rolling similarly to a BJJ class.

Interesting. The ISR is a bit different.
