Honestly, I have no idea. Could have been a falling out with Darren. Could have been that he just wanted to go out on his own. But you're correct...there are politics in pretty much every art, Krav Maga not excluded. In my area, I have a KMWW affiliate school. Also within a few hours drive/train ride, I have 2 other orgs, 1 the KMF and the other the IKMA. IMHO, there seems to be less 'drama' for lack of better words, with those orgs., but again, thats just my opinion.
