i have read the other comment on here and think that many people miss the point . this documentary illustrate the banality of evil very powerfully while it do not preach or try to shove the maker opinion down the viewer throat and like so many other so called documentary do . this be not one of those documentary which show edit footage and historical footage a a mere backdrop to put forth someone opinion . that what make it so powerful and to see the people who commit this incomprehensible evil and those that suffer it ask their own question and try to make sense of it all and try to justify it and analyze their role in real time a the camera roll . it be very evident that this be the first time many of them have question themselves on what they have do . the repetitive re enactment and explanation of the guard day to day activity be horrific in their normality . even after all these year and after all that happen and these men have no qualm about show the world their routine and make it obvious that they do not equate their action directly to the effect it have on their fellow country men and woman . one have to remember that the guard be brain washed and indoctrinate by the communist at a very young age . this can be directly equate with what happen in the world today with militant islam . theyre create their own amoral killer and fanatic by indoctrinate and brain washing child . if nothing else and this documentary show how once indoctrinate at a young age with fanatical ideology and all that remain for the rest of that person life be an empty shell incapable of comprehend basic humanity .
