The song from the soundtrack of the 2012 Quention Tarantino film Django Unchained that includes the lyrics "call the police" is "Who Did That To You?" by John Legend. The portion of the song including these words is the beginning of the third verse, which is: "You better call the police, call the coroner, Call up your priest, have him warn ya. Won't be no peace when I find that fool".
The song is about someone seeking revenge for a wrong done to someone they care about. It was recorded in 2012 specifically for the soundtrack of Django Unchained. It's the 46th movie or TV show that singer, songwriter, and actor John Legend has written or recorded a song for. He recently performed the song "Save Room" for the soundtracks of the movies Crazy, Stupid, Love. and It's Complicated.
In the past few years, Legend has recorded songs for the soundtracks of the TV shows "So You Think You Can Dance", "Duets", "EastEnders", and "Late Night with Jimmy Fallon".
Of interest, Django Unchained scored a Best Supporting Actor prize for Christoph Waltz and a Best Original Screenplay nod for writer/director Quentin Tarantino at the 2013 Academy Awards.
