Human Knotting Video

Episode #2 of the A&E Television Network series Surviving History contains a segment on Human Knotting.
Unlike the Siamese Human Knot, the torture involves ropes, but the video does seem to suggest at least some links between reality and fiction.

In this vid-cap from the video, two members of the Thugee cult in India interrogate a victim by tying him in a Human Knot.

The next two vid-caps are of what the program calls a "pretzel torture."
Information about such positions, also known as anundals as well as Human Knots, has been posted on this site for years.

This final vid-grab also echoes some of "Batman's research."
