I don't know, he's riding a few very thin lines here, - some that he may not even be aware of himself. Obviously, his introspection and logic are, at the very least, compromised by his extremely recent breakdown and desires toward terminating his own life. These types of internal conflicts are long in coming and LONG in addressing. Yes, there is the benefit of catharsis, but there are also the dangers of transference and continued repression, among others.
His motives cannot truly be known. While we all hope they are for another, there is equal possibility that they are an attempt to somehow engender sympathy for his daughter, or for himself. These are things that, while we are not privy to, must still be considered when trying to eke out the truth.
Were my child missing, would I be open to the presence or association with a principal party in a case such as the Anthony's being superimposed upon my currrent situation and investigation? I've thought hard about this (and, yes, I'm a parent of young ones), I don't think I would. I don't see the advantage that it would bring to the investigation since coverage had already gone national. And, I would not derive any emotional support from someone that I knew was living in a world of denial where there own family was concerned. The very crucial differences would far outweigh any similarities, - to me.
There are other considerations, but these presuppose the rest and are the most pronounced. Even giving George the "benefit of the doubt", and taking it at "face value", I think He's a thin sheet of ice masquerading as an iceberg. I concede that any of the variables are possible, - including that everything is innocently fine, - but I, personally, wouldn't be willing to put his eggs in my basket.
These very real possibilities are hard, and may go against popular sentiment, - but, nonetheless, they are VERY real and VERY pertinent.
I do wish George the best, but I think he is in no TRUE position to help another until he can truely help himself. A psychotic episode, as he has suffered, doesn't assuage with a bandaid, - it requires the equivolent of psycho-surgery requiring a long series of painful introspection, more painful acceptance, and the time for it all to be absorbed into his life. He has a VERY long row to hoe, but given the man and pressures as a whole, I would have to wish him the best but deny his influence.
I acknowledge that there are many ways to view this, which is a definite part of the problem. This is only an opinion, - as I see it.
