Stop the presses. I am actually going to agree, on the surface at least, with gord.
This means the world is probably coming to end, so some of you need to get right with God and all that. You can probably skip returning those library books and
Seriously, I don't fault the McCanns for not flying back to assist or pay for any searches in the resevoir. If they are involved, then they would logically stay home. If they aren't, then flying to every search location is not feasible or practical. Gerry McCann is back at work, the twins are back in their home routine, neither parent is free to just take off and search multiple possible locations.
If Madeleine had been taken near their home, I would expect them to be out with all searches, but not to fly anywhere else for searches. As for paying for it, again, if they are involved, then why would they want to give any money for something that they either a) know is futile, because they know where Maddie is or b) help produce evidence of their guilt. If they are not involved, then using any funds anyone offers up only makes sense. If you take small contributions then why refuse big ones? It's one and the same if you are collecting donations at all.
Of course, this means that one can't play the "the McCanns are criticized for everything they do, no matter what they do they are going to be condemned." We'll have to retire that one like a Barry Bonds trading card.
