"Results". "Details". Never "evidence".
Gavin said he was confident in his conclusion. He then went on to describe numerous activities; interviewing current and former AMI executives, Middle East experts, cybersecurity experts, current and former advisers to Trump (?), whistleblowers, associates, and others targeted by the Saudis.
That sounds to me, like an awful lot of smoke, and zero definitive evidence. What he didn't say he had? Forensic evidence from the phone. DKIM signed email trail, confession from a co-conspirator, etc.
I have no doubt there is a compelling story here. I have no doubt that this could theoretically fit the Saudi MO. I certainly have absolutely zero doubt that the crown prince is an epicly murderous duplicitous asshole. I might even believe the Saudis have some ways to remotely infiltrate certain iPhones (but I would bet it requires compromising the carrier).
None of that would lead me to conclude the Saudis tipped AMI without just a little bit of non-circumstantial evidence.
