u're walking down the sidewalk at midnight in Las Vegas. Right now the sidewalk is so empty, when u walk with ur groceries, suddenly u hear someone screaming from a dark slum alley squeezed by two tall buildings. U were unbelievably surprised, then u walked towards the source of the sound, then u peeked from afar. U see a tall and muscular man casually stepping on the face of his victim who has fallen to the ground, he even smokes a cigarette. While behind him, his men stood watching.
