Since it sounds like a paraphrase of a quote, I'm leaving it "gaol", but if it's not McKinnon's own words, then "prison" would make more sense.  In the meantime I think many English speakers (American, Canadian, and non-native) may not recognize this word, so I thought it would be helpful to link to the gaol wiki so people know it's not a typo.
