Read Grimm & Precinct 17 pilots this morning over coffee... while drastically different, they are a=similar enough that if NBC choses to do a magic/cop drama, they're only going to chose one, and I think Grimm may have a leg up!
Look up "Special Unit 2" on imdb... was a Magic/Cop series that lasted ~2 seasons back in 2001/2002 ... most of the setup is the same but the cases are a bit darker in Grimm and P17
