i only remember a scene, i watch it about 15-20 yers ago

It starts with the fact that two guys (perhaps they were brothers) are under brutal arrest. The cruel guard says to one of them: "You can go home, you are free", so he (probably it was a tall blonde) walks away calmly, unhurriedly. I remember that this prisoner was walking down a long corridor. Then the guard treacherously shoots him in the back. Then he says to the second prisoner (probably even bending over his friend's body): "And you will tire yourself"
