When a man witnessed a mother allegedly abusing her son with autism in a city street he let her and the whole neighbourhood know what he thought.
The shouting match plays out as someone in an upstairs apartment films the street scene through a window of a North American city.
The mother and her children were playing around a stoop before they head off down the street while arguing with the man.
Her children and other people on the street watch on as the argument spirals out of control.
According to the post uploaded to LiveLeak on Sunday, the man – who says he's also a parent – saw the woman abusing her boy on the street and could not ignore it.
At one point during the highly-charged argument the boy falls to the ground and begins flailing about.
The profanity-laden video has raised a few eyebrows, with commenters commending the man for intervening to stop the alleged physical abuse.
However, there are a number who objected to the man's aggressive approach and profuse use of swear words in front of the children.
