Who are today’s leading instructors in self-protection? In the UK, the likes of Geoff Thompson and Peter Consterdine pioneered teaching about self-protection. What was pioneering was how they based their teaching on a wealth of first-hand experience (as opposed to dojo experience). Is there anyone like Geoff and Peter who’s teaching nowadays? Has self-protection further evolved? I think knife crime in the UK has increased since Geoff and Peter’s days. CCTV is another difference since their time. What else has changed and who’s now teaching contemporary self-protection based on practical experience?
