A major problem seems to be that &#x27;ex-cops&#x27; don&#x27;t like inspecting &#x27;cops&#x27;.  However, balancing powers between three entity&#x27;s seems to work well.<p>Agency A inspects agency B, agency B inspects C, C inspects A.  That way B can&#x27;t threaten A.<p>As a bonus it really set&#x27;s things up so they get antagonistic with each other.
