Suspects give police the silent treatment

According to the BBC those arrested and questioned by the PSNI have told the police nothing, which is in apparent contradiction to Gerry Adams’ plea for anyone who knows anything to tell what they know. We’ve also had reports that Brendan Devine, McCartney’s companion on that fateful night, has subsequently withdrawn his orginal intention to offer police his own account. The police ombudsman described the intimidation of witnesses as horrendous. Is the political dilemma for Sinn Fein too painful to bridge? Or is this simply a case of criminality let go and out of control?
