Ferryman, by all means you are more than welcome in attempting to convince me. However I must warn you that based on what I have seen so far, especially regarding the McCanns behaviour, you will have an immense if not impossible job on your hands.
You would need to provide enough evidence of an actual abduction to outweigh my suspicions. For me this lack of evidence along with the McCanns behaviour is the reason for so much anti feeling towards them. Their conduct regarding the e-fits does nothing at all to help their own cause.
If there had been clear, concrete evidence of an abduction then I would have no problem. Unfortunately this is where the whole argument falls woefully short for me. If I was to abduct a child my whole focus would be to snatch the child and make my escape as fast as possible. It would not be to make every single minute aspect of the abduction from start to finish untraceable which is exactly what has happened in this instance. For me that would require a lot more time and planning than the abductor appears to have had.
If the McCanns were involved in the death or concealment of their daughter then that
also appears to have been exceptionally well hidden. It would also have required time, planning, and a level of knowledge of the local area that the casual tourist would be hard pressed to acquire on the spot.
I respectfully disagree that abduction requires a special level of proof that the other possibilities in this case do not. (Maybe that is not quite what you meant, but that is what is implied). Killing and / or disposing of a child, perverting the course of justice, and conducting a campaign of fraud on a massive scale, are profoundly serious crimes for which the punishment would be many years of incarceration.
Very high levels of proof would be needed to prove or substantiate such things. 'Suspicious behaviour' over e-fits and the like is far from enough.
