So you doubt Hurst's word? Why? One can change one's stance as new information comes in as Hurst seems to have done over time. His apparent change of opinion/stance/theory over time does not mean he is lying. I choose to believe what he says because it seems, to me, the most plausible answer. Nothing is ever proven 100%. Somewhere, somehow, there will always be a smidgen of doubt. I gather from what you wrote that you choose not to believe what he has said about the tracking dogs, Wendy's, etc. That's perfectly fine. You can believe whatever you want and so can the rest of us.
But until something better comes along, until something is proven as near 100% as possible, I choose to believe what Hurst has said and I stand by my theory until it is proven wrong.
No hard feelings
