IMO, the original scenariob was mis-titled, as it seems more like a dilemma, than a "real problem"? This was likely a reason why the discussion evolved towards a humourous note.

The way I see it, problems can be solved (call the police, or throw the nasty thing out). Dilemmas need more thoughtful management, as they involve a personal ethical issue - the nasty smelly package was entrusted to me to take care of and pass on to a neighbour, shall I betray this trust?

Oh well. By calling the police, it ended up being a problem that will likely be solved in one manner or another, most likely with few negative consequences.
