I don't think it sends out any such indication of the type you are suggesting, it's simply a recognition of fact.

The "fact" that publicity does/would prevent victims of sexual coming forward - A "fact" that most, including myself, accept.

Is it wrong to ask why lack of anonymity has such an affect when in general the same can't be said in general about victims of other sorts of crime?

If it's not a perceived sense of shame by either the victim or society, or both, then what is the reason for this "fact"?

If you are actually concerned with societies perception on this issue, to save confusion and misunderstanding,you would be better advised to address that issue in a clearer way, and not confuse it with other issues.

What other issues am I confusing it with?
