Mohammedan dogs are not required by the rules of their death cult to be truthful with infidels.
Their sworn statements have no credibility with any sane human being.
I question the sanity of anyone who would even participate in a process that acquired such statements.
Their ignorance of cult rules makes them incompetent to conduct such inquiries.
You cannot rely on this type of information. The SS and Japanese used these tactics in WW II and most GIs laughed about the line they gave their captors. Another problem arises when these stories get out and the resistance increases. An enemy will fight to the death rather than take a chance on getting captured.
