I believe the only responsibility the "crime victims" should bear is their sense of naivety on their behalf, of which total ignorance (or living in this fantasy that nothing could happen to you...ever) is what it is - total ignorance - based on a sheltered upbringing and not having a trained eye or instinct for danger. But if you don't know - you don't know, so how could you be held responsible for anything. But if deep down you know your better judgment and still decide to take the risk of leaving a bar at 2 AM with a stranger - then you are responsible in part for your victimization. The only time someone does not take some responsibility for their victimization is when their attacker is totally in the wrong applying extreme force whereby the victim was not given an option to think or escape.
