I wanted to expand on my first answer but it's too late to edit. Taking this back to the original question I think this scenario is a time you definitely want to tell the police and Lawyers all about your training and skills. If I were to choke someone out through my lawyer talking for me I'd explain all my training in the use of chokes, I'd explain the difference between blood chokes and air chokes, I'd explain how I've used chokes 100s of times in training or tournaments, I'd tell them I've been choked out a few times and know the effects, I'd be as detailed as I could about my training including ranks and any tournaments I've done. I'd explain how badly I could have hurt the person and why I didn't. So yeah in this case I'd definitely tell everyone about my training.
