The group received an armed escort from HMP Addiewell in West Lothian to the High Court in Glasgow each day of their trial, which lasted 14 weeks.

Police carried out daily checks for explosives at the building, while armed police patrolled the area.

Their trial was one of three cases where police had tighter security measures, including a helicopter patrol, since the start of last year.
