Seems to me, this guy is honest but got used by Fujitsu (in the past) and is currently giving evidence in a public inquiry regarding the Company (Fujitsu), and also the British Post Office Ltd. Long watch.
Absolutely fucking nonsense. He’s on criminal charges for perjury. Watch the whole 4 days of his testimony. Lie after lie after lie. He had zero clue what he was going. That’s no defence.
