Also, I'm not clear on this, but does Bruce know Danny's story here? I'm sure he would sympathize with her personally--really the only difference between her and him is that she's administering punishment while he just hunts criminals down and tries to get them put in jail.
But I can dig the set up of Bruce and Diana basically being on either side of that classic ethics question about whether it's wrong to steal medicine to save a dying person. Bruce is the law, Diana is the humanity behind the law. (Taking the traditional male/female roles too.) The two of them are interesting mixes of the two as characters, though.
