First, Signal 88 and 88 Tactical are two different companies. 88 Tactical is the one you're looking for. Most of their adult curriculum is focused on fighting. They also offer tactical medicine and survival classes but I'm not sure there's anything on their course list that delivers what you're looking for. Perhaps one of their cadre, active on this forum, will correct me.
I've seen an abbreviated version of Chris' Legal Aspects class and I would highly recommend it. Chris knows that, if there is demand for his non-range courses in Omaha, he has a place to hold them.
I've also worked closely with Ken (SempreFiGuy) but I'm not sure if he offers a class similar to Chris' Legal Aspects class. Like Chris, Ken knows that there is a non-range training facility available to him in southwest Omaha.
