There are some things that we do try to keep close to the vest; they're tactics and approaches we use to try to ensure we go home at the end of the day. But, honestly, most of them can be found out there.
While many academies do video record most of the training for liability reasons -- it's not necessarily stuff we can lay hands on and share publicly. And I'm not sifting through everything that pops up on a web search for them to find some good ones. You can do that. The one about the hat was actually being well conducted -- but it wasn't what you wanted to see. You want to see training where people fight. I get it. I'm just not wading through videos to find that. And, even then, without all of the context, it's hard to evaluate and too easy to twist.
