I remember a similar story a while back about a similar school in Jamaica. The children were so baldly mistreated they were malnourished and suffered from severe infections. The places didn't allow the children to see medical professionals, and their approach to dealing with a sick child was to give them an aspirin and have them continue the normal routine of torture and brainwashing.
Places like these are beyond sick, and the scariest thing is, from watching the clip of that trailer, is that it didn't even look as bad as some of the other places out there. As a parent you really have to ask yourself if you can really trust any organization that believes kidnapping your child in the middle of the night and dragging them around like an animal even in public at the airports and such is the best course of action.
Places like these make me really sick. Their methods are basically textbook brainwashing techniques, and the permanent damage they do to the people who graduate, is scary. What is worse is how the children get so brainwashed that they even willingly take part in the degradation and torture of new initiates. Many of these people only realize after they leave and go for extensive therapy just what they did to others and how they regret their actions.
