I'm Joc Rose and I'm currently the PBs Elder on the Council. I encountered PBs in 1991 (or 2 - can't quite remember) when I attended Di Margetts' presentation at Milton Keynes police station. On that occasion a lightbulb went on over my head which has never gone out since (must be an LED), and though I'm retired now and no longer professionally involved with PBs I still use the process all the time.
