We’re starting a new EWI series with A spotlight on… the Post Office Horizon Scandal which looks at how the Post Office failed to listen to, and act on, expert advice. EWI member and IT and digital forensics expert, Jason Coyne, first spotted errors in the Horizon system in 2003 while working as a Single Joint Expert, only to have his findings dismissed by the Post Office. Jason tells us more about his involvement in the case, including how he later acted as an Expert Witness in the sub-postmasters’ case against the Post Office.
