Based on not much more than experience in management, once an employee starts "working" outside his employer's remit, it can be very painful for said employee. The company cannot condone, defend or pay any penalties for those actions that are criminal or in conflict with company policies, procedures or legal obligations. I don't believe either captain is immediately in jeopardy, but if the captain directed the introduction of the police and the police are found to use excessive force, the captain might become an acessory. Lots of assumptions there.
