McFarlane kept his silence over Tidey abduction
Brendan McFarlane denied the charges brought against him in the Special Criminal Court.
Gardai gave evidence about questioning McFarlane after his arrest and said he remained silent when asked about the kidnapping of the then Quinnsworth boss, events at Derrada Wood, Co Leitrim, and the IRA unit.
Gardai said there was also silence when it was put to McFarlane that he was wearing a garda uniform when Mr Tidey was abducted from his home in Rathfarnham, Co Dublin; when it was suggested that he was involved in the shooting of a garda and soldier; and when it was put to him that the kidnappers took over a house in Castlebar, Co Mayo, after they escaped the wood.
The prosecution had also intended to put a number of items before the court, including a milk carton, a plastic container and a cooking pot, on which, it was claimed, they found McFarlane's fingerprints.
The items, stored at garda headquarters, were lost during renovations.
McFarlane denied garda claims that he had admitted being in Derrada Wood while in custody or telling detectives he was "prepared for the worst".
He was acquitted of the charges and focused on his case in the European Court.
