T here is a saying attributed to the U.S. President
Lincoln, that the law may declare a steer to be a cow but
the law can not make it give milk. Similarly a building
may be declared a gas chamber but that does not make it
work for gassing people.
The U.S. has used the same gas for execution of murderers
for some eight decades. It is used because it is one of
the most lethal gases other than nerve gases. It is not
a gas one uses casually even when executing just one person
in a small chamber.
There are procedures for exhausting the gas and for neutralizing
the traces that inevitably remain. There are numerous construction
considerations. This link
http://theelectricchair.com/gas_chamber_protocol.htm
gives an excellent summation of the matter.
http://www.roadsideamerica.com/set/crimegas.html has
some pictures of chambers implementing these considerations.
Scaling up a gas chamber to a capacity of even dozens,
much less hundreds or thousands, certainly must comply with
those requirements as a minimum. The resulting large gas
chamber should certainly bear some resemblance to the pictures.
Certainly any building called a gas chamber must certainly
have much more than just holes in the ceiling to meet the
requirements of the protocol and actually be a gas chamber.
Rather than show us features that would make it possible
for these buildings to actually be gas chambers they rather
concentrate on showing us things from stories of people
who claimed to be eyewitnesses.
Holes here, a door found on a waste dump there, an exhaust
fan found some place else. It rather more appears to be
an episode of Junkyard Wars, a scavenger hunt, than a serious
effort to make an engineering case for these buildings being
gas chambers.
When addressing the serious engineering requirements
they dismiss them with glib answers rather than serious
engineering analysis of what they claim would work just
as well.
Showing me a hole shows me only a hole. Show me the air
tight seals that will work as well as the doors in the pictures.
And if the seals are said unnecessary, show me the engineering
details as to why similar seals are not necessary and if
you find different seals, show me how they worked in egineering
detail. I do not accept glib dismissals even from engineers.
Declaring a building to be a gas chamber is not even
a first step in demonstrating the building could in fact
have been used for gassing people in the manner claimed.
