it does seem to show that "fairy" and "leprechaun" are distinct concepts, which is not entirely a contentless statement.

But everyone knows that LEPRecon (Lower Elements Police reconnaissance division) is a job title and leprechauns are, in fact, fairies. This leads me to approximate the question and answer "most leprechauns are above average fairy height". This is to be expected for cops in general, above or below ground.

It seems that even if leprechauns are fairies the concepts are distinct.
