And regarding 'Fanny Blair' which Kitty mentioned, that's another one in which the narrator is far from neutral. We are told directly that Fanny has lied in court, and when in the last verse the mob declares Higgins innocent and Fanny a perjuring whore, it's pretty clear that right-minded people are expected to be on the same side.

Anyone whose circle of friends includes teachers will have heard of instances in which children make false accusations of physical or sexual abuse. Nonetheless sexual abuse of children is real and not uncommon, so to sing 'Fanny Blair' runs the risk of appearing to downplay that reality.

I suspect strongly that FB would have been heard scarcely at all in the folk clubs of England, were it not for the magnificent tune.
