My comments regarding the male's responsibility to report the crime has always been with regard to the legal aspects of this specific case. If he expects to be legally absolved of any responsibility, then he has the responsibility to report the crime within the time period proscribed by law. Further, in this specific case, if he was initially unaware of any legal responsibility, he certainly became aware when the State first informed him of the situation.
At that point they also informed him that he had 90 days to contest the paternity, and by that time he was apparently 20 years old, a legal adult. Instead of taking the responsibility, he chose to ignore the situation. Legally speaking, he is now on the hook for child support. Had he taken any responsible action at any point, my take on this specific case would be quite different.
Morally speaking, I do not think the State should be going after rape victims for child support. I would be fully behind any initiative that would correct such a moral failing in the law. Even were such a provision enacted, however, there would need to be a conviction for rape against the female in this case for the State to take action in furtherance of that provision.
At this this juncture, let me be as clear as a judge: I do not care about right and wrong. I care only about what is legal and what is not. Specifically, I'm interested in knowing whether he had a legal responsibility to report the crime, and the reason I want to know that is because that will tell me whether or not his inaction was or was not some kind of failure on his part.
You said, "Further, in this specific case, if he was initially unaware of any legal responsibility, he certainly became aware when the State first informed him of the situation." I don't care about whether or not he was aware of the purported responsibility. If he did in fact have a responsibility to report the crime, then that is so regardless of whether he was aware that he had a responsibility to report the crime. What you say implies he had a responsibility, but I'm still hesitant to bite.
You also said, "If he expects to be legally absolved of any responsibility, then he has the responsibility to report the crime within the time period proscribed by law". Statements like that make me cringe with uncertainty.
He may have had 90 days to contest the paternity, and there may very well be legal consequences for not contesting it, but in no way shape or form did he therefore have a responsibility to contest the paternity. The potential for legal consequences doesn't in and of itself bestow responsibility. If we are legally required to do something then don't do it, then you have a basis to claim a failure to live up to a legal responsibility, but there being legal consequences for not acting is insufficient to claim there was a responsibility.
If he taken the responsible action? Don't confuse being responsible with responsibility. We have a responsibility to show up for jury duty when called upon, but we don't have a responsibility to exercise our right to vote, but if we choose to vote, we should do so responsibly. He could have chosen to report the crime, and he could have done so responsibly--perhaps by reporting the facts as accurately and honestly as possible, but to suggest there was some legally bound duty or legally dictated obligation (hence, an actual legally required responsibility) doesn't portray a situation that accurately reflects the facts of the matter--at least not so far as I can tell.
