The song theme of the popular Brazilian film Tropa de Elite [Elite Squad], about police corruption in Rio, has become background music for the Pernambuco's Police Forces. They sang the lyrics by Tihuana when were called to calm down a rebellion in a prison, as reports PE Body Count [pt]: “The chorus “Elite Squad/ A tough nut to crack/ get one/ get all/ will also get your back” was considered a provoking and intimidating act by the inmates’ wifes.”
