So the point is that this is easy technology and the Germans were readily using it IN THEIR CAMPS. All they would have needed to do is make it so that a secure barrier was between the blower apparatus and the condemned, and voilà.
That the Germans put zero thought whatsoever into mass-murder is very telling. Very telling, indeed.
Remember, the EXTRAORDINARY exterminationist claims are not an occasional prison camp murder--these happen sometimes in other institutions besides "death camps."
Case in point--the Papago Park World War II PoW camp at Phoenix/Scottsdale, Arizona. On March 12, 1944, German Kriegsmarine PoWs hanged an alleged informant who was brought in from another camp for this nefarious purpose. The man, Werner Max Herschel Drechsler was recognized immediately as a stool pigeon from a camp in Texas, and within seven hours the collaborator was found dead hanging in the Papago camp shower in his underwear.

Seven perpetrators of the murder were themselves hanged at Fort Leavenworth shortly after the end of the war, in the last military executions held by the United States.
Again, the point is that with "Death Camps" and "industrialized mass-murder" we are not talking about a FEW killings or executions, of course. That means another kettle of fish entirely.
