I wouldn't call the police 'trained experts' in solving moral dilemmas =P. But, if there were trained experts to call, then that's a pretty boring hypothetical. Obviously you call them, unless you are a greater expert yourself or you think they have some kind of bias against the correct solution. I have no idea of what that kind of hypothetical situation would be intended to illustrate.

Anyway, if you want to talk about another hypothetical, why not answer the question you were asked, then tell them that you have a hypothetical of your own which you'd like them to answer? That wouldn't count as fighting the hypothetical.
