Behind Enemy Lines

I'm not really sure why such deep research as Irving is alleged to have encouraged is needed. You don't need to be an academic to realise that the handles of the ventilation shutters for a shower block should be on the inside rather than where they were, the outside.
The entire transcript of the Belsen trial is enough to convince anyone that the claims of being short of food, water and medicines was not as widespread as is often claimed. The British Army established a water supply in 2 days of entering Belsen and the nearby German Army barracks had a bakery with enough supplies in stock to produce tens of thousand of loaves of bread a day.
I'm not against challenging the accepted historical details but Irving doesn't, what he writes is lapped up by those who share his right wing perspective and they will never bother reading any other research. He adds nothing to the debate except propaganda.
Making assumptions and taking peoples word for stuff isn't part of the historical method. The bakery claim for example would need to be investigated a) to prove it's veracity and b) to understand why this food wasn't sent to the Belsen camp (I can think of 2 possible reasons off the top of my head).
Citation needed for the ventilation shutter claim too - does it actually exist, where is it from, was it part of a gas chamber, was it part of a gas chamber that was used to kill people etc.
