Only 12 people can be executed per day in a U.S.A. gas chamber if it was being used 24 hours per day without accidentally executing the people running the gas chamber claims expert at about 14 minutes into the video
At this rate & with the concentration camp facilities 6 million could not have been gassed to death during the time frame of the holocaust without the guards accidentally gassing themselves to death
