It's Portuguese (From Brazil, the nigger variant of the language)
They get out of the car, a lot of mumbling can't understand.
After he is shot the first few times they say
"You liar, you liar" (he says "safado" which is a general term for someone who is untrustworthy and dishonest)
Then he says "Get me more ammo" that is when the guy in white runs to the car to get more ammo.
Guy on camera says "He really had to die" other guy agrees and says "Yeah he did"
Then he says " You're gonna take a few more 20 so you become smarter" meaning that they are gonna shoot him again. Before the video cuts he says "Go with god"
Just brazilian niggers being brazilian niggers, don't mind the medium to upper class that migrate to Portugal and shit, but these shit tier ones need to actually be nuked one day. One of the worst type of people to know.
