As long as it is seen as a dispute resolving mechanism, rather than as police, I think it would work for both (indeed, one of the problems with the ArbCom right now is that it is both dispute-resolving, and police. Maybe we need both functions, but they call for different mechanisms -- a dispute-resolution process does require, as Fred has insisted, that the committee look at the behavior of "both" parties. But this is possible only because there are two or more parties. I think the policing function requires a committee that can talk to users who violate policies even when no one has filed a formal complaint).
