The whole "crossover law enforcement questions the Winchesters" is sort of a mini genre of its own in Supernatural fandom - there's a lot of them - but this is far and away the best of them. It works perfectly with both fandoms, has fantastic characterizations, and the plot is great. It's got cute moments, clever moments, and lots of funny moments. This fic went straight on my top best fics ever list - it's publishable quality writing.
