Thus the early vague and unreliable rumors were replaced by the detailed steam chamber report, whose description of the killing buildings is the foundation of all later accounts.However, the Critique already addressed this point, noting that "steam is, after all, a gas, and it is not difficult to see how the anonymous source describing steam to Wasser could have deduced that the victims were being killed with steam when witnessing the opening of a gas chamber and mistaken the emanation of exhaust fumes from the chamber for a lethal sauna." It also notes that gas was specified by Milgroim [Milgrom] in a testimony given in Bratislava on 30.8.43. I am therefore entitled to conclude that Jansson is engaging in a "falsus in uno, falsus in omnibus" fallacy that tries to reduce the whole of Treblinka witness accounts in 1942-43 to "steam", and attempts to claim that "steam" invalidates all the other details the witnesses supplied.
Jansson also gaffes in his assumption that we can only be sure that nobody left Treblinka eastwards if there was "a 24/7 watch on Treblinka to make sure that Jews never left the camp." Jansson seems unaware that Polish railway workers were reporting to the underground, despite this fact being noted in the Critique.
