It makes sense to have watchers to watch the watchers because their respective job descriptions are different. One's task is to watch for "bad actors" and the other's job it to watch for bias within rendered judgments. Those are two different tasks requiring two different microskill sets and bodies of experience. Exemplars at each task may also represent two different personality types.
