I dont do Wikipedia,

go to the Institute for Historical Review.
They are not so "selective" with their information.
No where does it state that Fred Leuchter was America's leading designer for penal gas chambers, using cyanide gas. He Knew his stuff.
This Wiki "fact sheet" is a hit piece.
Research what happened to Fred after he dropped THAT bombshell, and then ask yourself...why?
