If you look really closely you'll see I edited my post (before you posted) as I became aware of the factual inaccuracy. You are quite right, Edmundson is saying the Tramadol was not supplied by Sky.
Again, this counters your assertion that Edmundson is motivated by revenge. There doesn't seem to be much of a hint about it. We don't need Peters words about Edmundson's mental state as Edmundson is quite open about it. Edmundson is going out of his way to highlight his own mistakes...but he is issuing a correction of Sky's account.
You might want to read this report of Dr Peters words on the matter and see if you can spot the glaring self-contradiction:
"However, the BBC says that the incident was not reported by Team Sky, because Edmondson told Peters he had not used the paraphernalia found in his room.
Peters said: “He fell apart at the seams quite dramatically. A number of things I asked him during that interview really alarmed me.”
Peters: "The welfare of the athlete was number one"
"I was now in a position where I can say the welfare of the athlete was number one,” added Peters, who spoke of how Edmondson had told him that he hadn’t injected himself with the vitamins because he didn’t know how to.
"This didn't quite ring true to me,” said Peters, who suspects that Edmondson may have been ill at the time. “I felt this is very odd from what I've experienced in the past when I've been involved with anti-doping issues. So I said to the team: 'I want to stop here’.”
Team Sky, who sought legal advice on the issue, did not report it to the relevant authorities, a decision Peters still supports.
“I suppose if I'm looking at safety issues I did think there was a really big risk this lad would be pushed over the edge,” he said. “I stand by my decision. I think I'd definitely have told them if I thought this young man was trying to cheat, but I don't think he was doing that. I think it was a panic reaction.”
He added: "We did it on good faith and decided on two counts. One, we didn't think he'd violated any rules and second and, most important, he was not in a good place."
So Peters didn't believe Edmundson's claim that he hadn't injected, and Peters though Edmundson hadn't violated any rules.
Nice one, Steve.
