Well, what were her justifications?
Btw, I think I found the link for the Imperial Army's Unit 731: http://www.sjwar.org/htm/731-07.html
It is a link, but I haven't had time to read through it. It's like 10 pages long, but worth the read.
That Imperial Unit was a real gas wasn't it? BTW, the Chicoms recently found the site ~ it'd been lost for over half a century.
