Propworn was not telling you to accost them but was warning that you could have legal trouble if you did accost them. As for what a CD/ED can do. A CD/ED is the safety rep for the AMA and is how the sanction is secured. If the CD/ED shuts down the event and leaves then the club would no longer have an AMA sanction. If this were what I were going to do I would immediately be on the phone with the AMA and would then make sure I filled the post event report out correctly and named the offender. A CD/ED is not responsible to the club for anything. They are there to just help sanction the event. If a club does not want to listen or follow rules by the same token then the CD/ED can leave and that club can get a sanction from somewhere else. At anytime I would not try to get violent or even yell. I would just warn a few times and after that I would pack up and leave. Letting theclub leadership know that they are now hosting an unsanctioned event. They can host any unsanctioned event they want and then it is on them to negotiate with the AMA (who I am sure would be very thrilled to work with them at this point) to fix any insurance issue.
