Err - does anyone else notice that at the start of the video everyone is perfectly posed with no movement, and suddenly there's a "takedown" - but with no change in balance or significant weight shift? The "victim" simply falls forward?
In a takedown someone of that size who's showing resistance, there would be a LOT of weight shift on the part of the staff members, and some kind of twisting movement of the supposed victim. But in this, all the movement is forward, and with no effort.
Sorry, but that one looks completely staged.
No. What I notice is that the clip starts at the point in which they've already taken her down to her knees, on the way to the floor. Someone on their knees with both arms held behind their back is not going to be moving much at all. What I also notice is that the woman to her right has her arm, not only behind her, but lifted about 8" and is twisting her wrist away from her body.
Takedowns/restraints are not reserved for violent kids who pose a threat to safety. It's a show of force to establish who's in control. Just like the wrist bending technique.
Get your partner to put you in a hold like that tonight so you can experience it first hand. Have him pull straight up while twisting your wrist. Don't leave out any steps.
Then search your soul to ferret out the reason you can watch this kind of 'treatment' and make light of it. Stop being naive. Did you read the thread which links to comments from the producer/programs? This series of "documentaries" were intended to educate, to show how Amurkins deal with difficult kids. Hope your kid survives program.
