Died: February 15, 2021. WHEN Ron Brown, the firebrand Scottish Labour MP, sprang towards a startled Mrs Thatcher during her visit to Glasgow in September 1982, William McDougall was one of the police officers who arrested him. Six years later, when Pan Am flight 103 crashed onto Lockerbie with such catastrophic consequences, it was McDougall who took a key co-ordinating role, establishing grid references and setting up search teams. His support, as his old colleagues recall, was invaluable, his ability to successfully liaise and unite with other emergency services a distinct advantage. And when he retired from the police, having become Chief Superintendent and appointed Director of Senior Training at the Scottish Police College, Tulliallan, it was into another career altogether, as Security Advisor to the Scottish Football Association.
