I said on the other thread, two conspiracy theories that have equal proof as any other theory are:
- Aliens
- She wasn't in the apartment at that time already
The whole point is there is no proof. No evidence of anything. And yes that could be because of shoddy police work, alternatively maybe there just wasn't any evidence there by the time the scene had been contaminated by everyone
I don't take the McCanns behaviour as proof of anything, nor do I judge them going to church or leaving the twins in daycare. I can understand all of that.
But the fact remains there is no more proof of a burgular or abductor than there is that the parents were involved.
Also iirc (it's from memory, it could be wrong) no one said the shutters couldn't be opened, just that there was no evidence of them being forced. Which there wouldn't be if they can be opened easily from the outside.
But again, why would a burgular or intentional abductor go through the window when they must have seen the apartment being checked every half hour and been able to see the door was unlocked. They may well have done this, I just think it's weird.
