Don't be ridiculous. Obviously, Lyndie Endgland's "sexual desires" were being well taken care of by Sgt. Graner.
Her "abuse" of the prisoners was calculated to humiliate them because of Muslim rubrics about nakedness, etc. and THEIR tendency to taunt, torture, and humiliate women...(not to mention the 12 year-old girls they raped.)
Lyndie turned the tables on them. It was at the advice of her superiors, the military interrogators who were way above her in rank.
That she seemed to enjoy it may have been immodest, but at least she didn't cut off anybody's head!
good point, palladin!
