I strange though crossed my mind.
Do you think it is possible, that all that "training" happened and was filmed way before "they claimed" it has happened. That's why people are so calm and NOT trying really hard to be convincing on the initial interviews and all the weird behavior on the day of. What if ALL these people though they were doing something good?
All of a sudden that "training" is pushed to the public as something real that has happened and some of these people are now BULLIED and forcefully made to continue this charade.
Obviously some were well aware of what was happening, but others were scared and wanted out. Maybe that is why there was 24/7 police attached to the unsuspected families, so they have no chance to revile the truth. At the and they were intimidated, scared and maybe "paid" to keep their mouths shut...
Do you get what I'm saying?
