Yep, they happen to be American (US or Canadian); not surprisingly, I'm most familiar with them. I'm quite sure there are others in the world doing good work, though perhaps not getting the attention or publicity. You might note that I did say "starting point."
But I'll stand by my comments about your desensitization drill. You're practicing standing at zero-range, and letting someone be abusive. Why? Does it teach something useful --or is there another way to practice a response that will be beneficial and desensitize you? It might work as PART of a much larger program -- but especially as a stand-alone offering? Nope, not something I want to ingrain in my students. It's just like a lot of so-called scenario training. I've seen stuff set up to prove the instructors can stack the deck and beat the students... and, at the opposite end, scenarios designed solely to allow the student to succeed, no matter what they do. A scenario should be designed to allow the student to succeed, IF they do the right things. This isn't necessarily a cookie cutter response -- but there should be milestones and keys to define success. It's complicated and hard; much more than just "lets do something... you're walking down a dark alley, and a guy jumps you..."
