BJ, Glad your back! Good to hear from you, and thanks for the comments.
I am a complete beginner when it comes to practicing martial arts, so if you have any training at all, you asking me is like Coach asking me for DB advice.
Funny that you ask though, as I have been following UFC since it's inception, and one of the popular referee's is nicknamed "Big John" and every time I see him now, I think of you.. LOL
Anyways, first, I seriously hope you do not have any kind of confrontation with the OM, for you and your kids sake, and if you think that is seriously a possibility, maybe you should inform that police ahead of time? Your kids don't need that on top of what is going on in your sitch right now, for sure. I hope that does not come to pass!
At 6'3" and 250, I doubt you have many people that bother you, so hopefully that will come to help you. Heck, I am only 6' and 190, and from what I have come to learn, people seem intimidated by me at times, although I don't see how, that is what they have told me. Everyone always thinks I am 6'2" or better when I am not. I have asked some people about it, and they say it's just a 'presence' that I seem to project, don't know about that, but I have yet to really have to get into phsyical altercations, and not why I am taking a Martial art.
That said, I can't speak to KM specifically, but it would seem a competent form for protection in the street, as that was it's basis in the real world, but I don't have any experience at all with it, or watching it, etc.
BJJ to me is also effective in real world scenario's. The objective is to neutralize any size advantage an opponent may have, while limiting your own exposure and risk, and to disable the opponent. BJJ locks and submissions if used outside the ring will cause devastating injury to joints, ligaments, etc, and that is the focus, through leverage and manipulation, where pure wrestling skills are not focused on that.
BJJ was born from Judo as well, so if you have background in that, it may help with BJJ as well.
