At its peak the total of shield volunteers in Baghdad numbered about 500, but the realization that the thousands needed to have a chance of stopping attacks on Baghdad had not materialized, combined with the failure of the United Nations to forestall war, meant that bombing was imminent. Many of the shields chose to stay; many others chose to leave. Still others, like O’Keefe, were ordered out by the Iraqi government. One 21-year-old human shield, Tom Hurndall, left Baghdad for reasons of safety. He went to the Palestinian territories where he was shot by an Israeli soldier while working with the International Solidarity Movement.
