"The Williams scourging is a clarifying cultural moment. It should be conceptually possible to separate the issue of the boys’ culpability from the question of whether the victim had the power to avoid the assault in the first place by behaving responsibly. Parents tell their children not to get into strangers’ cars not because they think that a stranger would be justified in abducting a child who did so, but because not getting into a stranger’s car is the best way to avoid kidnapping."
Indeed. These are two separate things which both merit comment.
