The only way to insure that only allowed cuts of meat are being used would be to hold all events in a fenced compound, have a TSA like search of all persons and vehicles to insure that no outside meat is being brought in then issuing each team their meat from a common pool provided by the contest. Nobody wants to do that.
Much like golf, competitor integrity has to play a major roll in policing BBQ comps due to the solo nature of the competition. You either have it or you don't.
As contests get bigger and bigger purses, should KCBS and other sanctioning bodies tighten up their rules/procedures and remove ambiguities? Absolutely! The worst thing for competitive BBQ rules is to go the way of the "unwritten, but everyone knows it's OK/prohibited" route. If it's a bad or ambiguous rule - change it for the better.
