In any large organization, there are basically two classes of rules: 1) stupid red tape rules that slow everyone down and 2) really important rules that you can never break ever. Effective people learn which rules fall into which group so they can break the red tape rules and get more stuff done.
Supervisors aligned with an organization's goals likely often view such external rules with contempt. It's not surprising they tolerate or support rule breaking as long as they believe it won't be punished externally.
