I think I've already explained that... The AR states.... none of the indications used to make the McCann's arguidos.... As it needs evidence to make the McCann's arguidos it looks, as though.. Indications... Is being used instead of the word evidence
At the time it only required "suspicion". The version after that specified "founded suspicion".
To be fair, the PJ had the woof videos. IMO, that constituted "evidence" but
only of the fact that the dogs alerted in locations associated with them.
However, it was in reality only ever an indication (IMO) as, to this day, there is no definitive answer as to what they actually alerted to as no concrete, physical, evidence was ever found, nor has it ever been clarified what other substances Eddie could have reacted to in order to eliminate those possibilities, nor was the provenance of the furniture ever verified, nor were the post-disappearance guests (4 lots of people) or other people entering the flat questioned as to a possible incident while they were there.
As to the car, it was meaningless. Unless I'm mistaken, I think I found (and posted) some time back that what Keela alerted to didn't appear to have even been the soup sample.
At the time, it was all the PJ had to go on and they ran with it, presumably in the hope of a confession.
