Its important to note that both Nascimento and Fraga are based in real people and the movie deal with a very present subject in Rio de Janeiro in the same way portrayed in the Movie. Brazilian viewer can clearly identify who are the main characters in real life. Deputy Fraga is a fictional representation of the real deputy Marcelo Freixo, who indeed conducted parliamentary investigation upon "milícias", which led to the prision of many corrupt authorities. Now he lives under 24-7 protection of police. Nascimento is the "near-super-hero version" of Fernando Pimentel, former Captain of BOPE and co-writer for the movie.
