"Polícia" is the fifth single by Titãs, from the album Cabeça Dinossauro, released in 1986. The song, written just after Tony Bellotto and Arnaldo Antunes were arrested for heroin traffic, criticizes the Police. According do Branco Mello, vocalist of the band, the album Cabeça Dinossauro had "much of that disappointment of being arrested and to know you are not a criminal".
Sérgio Britto recorded the first take of his lead vocals while overhearing a conversation between producer Liminha and Evandro Mesquita about spearfishing, which made him angry. He wanted to record a second performance, but his band mates convinced him the first attempt was fine.
The song was covered by Brazilian band Sepultura. It was included on their albums Blood-Rooted (1997), Under a Pale Grey Sky (2002) and also on the Brazilian edition of Chaos A.D.. Originally it was released as b-side on the Territory single, released by Roadrunner records.
"Polícia" was featured in the soundtrack of Elite Squad. A version of the song was used as the opening theme for a Rede Globo TV series called Força-Tarefa.
