Operation Nimrod - The Iranian Embassy Siege

After the end of the siege, PC Trevor Lock was widely considered a hero. He was awarded the George Medal, the United Kingdom's second-highest civil honour, for his conduct during the siege and for tackling Oan during the SAS raid—the only time during the siege that he drew his concealed side arm. In addition, he was honoured with the Freedom of the City of London and in a motion in the House of Commons. Police historian Michael J. Waldren, referring to the television series Dixon of Dock Green, suggested that Lock's restraint in the use of his revolver was "a defining example of the power of the Dixon image", and Maurice Punch noted the contrast between Lock's actions and the highly aggressive tactics of the SAS.
