CNN PRODUCER NOTE London-based owenm took part in the city's massive anti-Iraq war protest on February 15 2003, barely a month before the invasion. Estimates for the size of the crowd ranged from 750,000 to one million, making it one of the largest demonstrations in the city's tumultous history. "The noise was deafening, especially as we marched down Piccadilly [in central London]," he said. "There was no trouble, unless you count the numerous fires that were lit in the evening at Hyde Park [where the protest ended] so that protesters could keep warm as it got dark." Simultaenous anti-war protests were held across the world, with a demonstration in Rome hitting three million participants. "I doubt I'll ever have the experience again of being united with so many people in one place for one purpose," he added.
