The movie "Elite Squad" is about Rio's special ops police unit, also known as BOPE; this is their logo:
This is the trailer (not too representative of what the movie is about imo),
And this is the full movie...recording quality seems pretty good
When it came out it was attaqed by all the usual phonies as a celebration of fascism. The people liked it though...in fact it's just an "honest" and gritty take on this very good police unit, I found it very enjoyable. Best scene is what happens to the leftoid college students. It's also about the (not distant) future of the US, pepper your angus.
