Regulatory Magic (From Harry Potter)

I am no fan of Harry Potter, but after watching Deathly Hollow Part 2, I am quite intrigued that the Ministry of Magic have one law enforcement department and one regulatory department.

The insignia you see above is for the Department for the Regulation and Control of Magical Creatures (Whatta?).

Anyway, this means that even in the world of magic, one needs law, and indeed, regulation. I don’t know who’s the regulatory expert there but maybe they are Hogwarts graduates?
