Omen Armed video - Brazil--Brutal Machete Attack

In this CCTV video, a group of guys is seen hanging out together late at night. Two cars then pull up and as soon as the hangout guys recognize the people inside (rival gang members, perhaps?) or notice that they are armed, they attempt to make a quick dash for it, but at least three are caught. What follows is an incredibly brutal machete and sword attack that left each victim for dead.
