I think that's what was said, and I think the documentary said that Corrie was seen in the disabled bay by CCTV.
I'm also wondering if....in the earliest press conferences and media reports it's said that Corrie was in his quarters alone, drinking and on the phone to Darroch, and then Corrie drives in alone to BSE. But then the police have got the CCTV of Corrie in that parking space 40 minutes or so earlier, which means that while Darroch thought he was talking to Corrie in his quarters, Corrie was actually in the car having a drink and chatting on the phone.
We've also heard 'speculation' that Corrie might not have driven in alone. What if, at the beginning of the phone call, Darroch thinks Corrie's in his quarters, and Corrie turned around to someone and said, "bye mate, I'll catch you up in a few after I've finished on the phone". To Darroch that would be a guy at the base going into BSE separately from Corrie. But if it's actually occurring in the parking space, then that would fit with Corrie driving in with someone else in the car? I have no evidence such an aside took place, nor that anyone was in the car. But if they were, would the police have necessarily corrected Nicola's assumption that Corrie drove in alone?
I find that often when you have conflicting info that each piece is true to the person telling it. And this speculation would explain why we have a claim that Corrie drove in alone *and* an unsubstantiated counter-claim that he didn't?
