No backinfo. The video, apparently from Brazil, shows a guy bleeding from a cut on the neck being pinned down and held in place by a man with a machete.
Even though I don’t understand Portuguese, I somehow presume that the guy could be a wannabe robber who was caught in the act and the angered victim is dishing out on-the-spot punishment. Of course, I could be quite off, so hopefully our Portuguese speaking friends can shed some light on this for us.
Props to Best Gore member @seraphim-serenata for the video:
