He may have meant that the media would be all over Jodi's funeral whether he was there or not, since the murder had been "big news" locally, ever since it had happened.
So just to get this clear? The person convicted of this girls death, the murderer who was suspect at the time - put himself at the fore of media attention not once but twice on the day of her funeral?
Now you may have your doubts upon this conviction but as it stands that is exactly what he is, and exactly what he was at the time. You put a ? around this lad arriving home and letting his mother know what he had done? I too do that, I find it highly unlikely he told her exactly what he had done, we as parents find this hard to fathom, of giving help. Are you saying as a parent, you would have allowed your child to go ahead with being interviewed on the day of her funeral and furthered this with a visit to the grave, awash again with media. Standing smoking with your 15 - year old son at her grave whilst those cameras were upon you, even without them being there? Or would you, as the majority of parents would have done, showed your respect privately? Honoured this girls life and death in a respectful private way, one that did not need the attention of the country, all eyes upon them?
No, surely not - which give insight does it not to exactly how their minds worked? And it does not show this meek, innocent lad doting on anyone, does it? It shows a lad who really did not give a toss, did he? - and why should he have?
