I don't understand the dilema...if you or I were to refuse a duty given us by our work we either do it or have no job....it is as simple as that...If I have a conflict of conscience with what my employer is doing I quit I don't cry foul on the company they are doing what they do because it is there business.In this case the business is police work...to pick and choose duties like this...wow...scary place to be...hope you are not in this mans beat when he decides his beliefs dictate he cannot save you from a gunner because of the religion you belong too...wrong precident indeed being set there.
Me personally I would only accept guarding places where beautiful neked women were and where they served beer.

I would thankfully do my duties there..yea uh huh.
