Unfortunately her superiors go free
The 'woman' is trash, just as the 'men' that participated in that crime are trash. I guess I am a little sexist, because I expect women to be above such behavior- the impression that comes across from this incident is that this was like a wild spring break with human prisoners being used as entertainment by drunken trash.
Such behavior does not exist without there being a lack of supervision... or even outright condoning of these actions.
