I agree with that roundabout, the angle of vulnerability is perhaps the key one here.
Despite what anyone else may think, I am vehemently AGAINST victim blaming in rape cases, or the McCann case.
However, as a parent teaching children to take responsibility for their actions, and living with consequences which come as a result of making bad choices, I think it is an interesting question to consider where the buck stops in cases of crime. Eg. I left my computer on the seat of my car and forgot to lock car. Someone stole it. Am I in any way responsible? Should I teach my children to be careful with their things, and more importantly, themselves? I don't think it is victim blaming to teach that - it is common sense.
But what I am trying to understand is how to explain to my children that they do need to be careful (not flashing money/ phones/ walking alone at night, yes even getting 'off your face' drunk), whilst not wanting them ever to feel responsible if they were raped, mugged etc.
