Los Angeles police have been caught on video mocking slain Ferguson teenager Michael Brown. A video obtained by the website TMZ shows officers at an LAPD gathering listening to a parody based on the song, “Bad, Bad Leroy Brown.” It includes the lyrics “Michael looked like some old Swiss cheese / His brain was splattered on the floor.”

Song: “And Michael looked like some old Swiss cheese / His brain was splattered on the floor / And he’s dead, dead Michael Brown / Deadest man in the whole damn town / His whole life’s long gone / Deader than a roadkill dog.”

The singer of the song has been identified as former federal investigator Gary Fishell. The LAPD says it is investigating.
