I find this particular line very interesting :
According to Mr. Seel's book, German shepherd dogs were unleashed on his friend, tearing him apart and devouring him before hundreds of witnesses.Such actions could cost an SS man his life. Nevertheless, capos (inmates responsible for the daily running of the camp) didn't fall under the same policy and were well-known for their brutality. Assuming this individual is telling the truth, it would be more likely that a capo is responsible than an SS officer. Usually the Germans are blamed for the behavior of the capos, but it is more likely that their behavior can be explained by the psychological phenomena discovered during the Stanford Prison Experiment. Himmler assumed that inmate wellfare would be better if other inmates took care of the daily running of the camp, but the oposite turned out to be true. The Stanford Prison Experiment has illustrated that if you give random imates authority over other inmates in a prison situation it is only a matter of time before things get out of hand and those with authority use extreme brutallity. This is especially true in harsh conditions. I don't think a single Holocaust revisionist denies that things got out of hand in some of the concentration camps and that some capos used extreme violence... with SS men either not aware of it or looking another way. Surely there were also cases where SS men went out of line, but when discovered by SS autorities these men were sentenced with severe punishments. Abuse of inmates by SS men was definitely not condoned or supported by SS authorities.
Anyway, I'd like to see some evidence of torture in civil society or some evidence of explicit torture by SS men in concentration camps... and preferrably hard evidence (eyewitnesses can be unreliable). Especially the first (evidence of torture in civil society) is interesting because because it can tell us something about how normal torture was in the Third Reich.
