You forgot the quotation marks around "men", because these males are nothing more than overgrown boys. Its sad, I think we are finally seeing the result of the slippery slope we have been slowly sliding down the past two generations (and yes, my generation is partly at fault..)
How do we know that it was a male that took the pictures? It could have been something she and some female friends around the base did one night for a laugh after drinking a few too many mudslides. One of her gal-pals might have made the mistake of leaving them where they could be found. We can't be sure that it really was a guy shopping for a buyer. Women can be very mean when they want to. Could have been a friend of one of the other female POW's who didn't like Lynch getting all the attention.
