This video is from Brazil, but that is in essence all I know about it. It appears to show a shot man taking his last breaths before dying. The man is in just his underwear and lays on a bed soaked with blood from apparent gunshot wounds in his upper body. The man is barely aware of himself – his agonal breathing seems more reflexive, than life sustaining.
The people who filmed the video don’t seem too concerned with the man dying before their very eyes. A still camera flash appears to go off at one point, which makes me think they are the police who shot the presumed criminal.
