In all seriousness, I would consider rendering aid to an on-duty officer if A) their status as a law enforcement officer was manifest, B) they couched their request in the language and tone of voice as a request and not a militaristic order, and C) in the language of the duty to retreat laws, I could act "in complete safety". If any of those conditions fails to hold, I'll not even consider aiding an officer. If they all hold, I'll still consider my own needs and wants before the officer's.
