Bay Area residents attempted a citizen's arrest of former Israeli Prime Minister Ehud Olmert, while he gave a speech to the World Affairs Council in San Francisco on 22 October 2009. Twenty-two people were arrested for challenging Olmert directly and demanding he be tried for war crimes and crimes against humanity in the Gaza Strip and Lebanon. Olmert has faced protests at Tulane University, University of Kentucky and the University of Chicago. The recent International Independent Fact-Finding Mission, headed by Judge Richard Goldstone, found evidence that Israel had committed war crimes and crimes against humanity during a three-week long attack on the Gaza Strip last winter, killing more than 1,400 Palestinians, mostly civilians, and destroying much of the area's infrastructure. In 2006, similar Israeli attacks on Lebanon killed 1,200 people. Olmert has refused to be held accountable.
