I suppose, in minimum security situations, then yes, female psychology could be a plus. But dealing with 'dangerous' people, then, no, I think it's reckless. And the women that choose to do it have something SERIOUS they feel they have to prove. Otherwise, they'd work elsewhere or in a women's prison. I feel like men who want to work in a women's prison would have similar issues, by the way..
Ad, as far as personal interest, suppose someone I cared about was sexually assaulted. Like I said, I'm biased. But a woman should't set herself up for that shit, anymore than I would drop my pants in a dark alley and bend over.
