Locally a group of catholic school girls just attacked and beat up a man who had exposed himself to them on several occasions. It's hard not feel a little happy when the normal power dynamics are inverted, but I agree with
Bob that this isn't exactly a "good thing," Vigilante justice should never be condoned, with the possible exception of when the legal system has completely failed (I'm thinking of, say,when racist murders go unprosecuted by local authorities).
