VIDEO : Michael Peña & Alexander Skarsgård New Trailer

Throughout the last several decades, there have been all sorts of movies about corrupt, amoral or violent cops. Usually, these movies are thrillers, or gritty urban action films (like Training Day), or morality tales in which the good cop takes down the bad ones (like Serpico.) Even comedies about less-than-great cops (like the Ferrell/Wahlberg comedy The Other Guys) are more about the cops being idiots than corrupt, and end up with the protagonists redeeming themselves.
