Demonstrators carry signs protesting the Conference on Security Policy in Munich February 11, 2005. Police increased security after U.S. Defence Secretary Donald Rumsfeld decided to attend the European security conference in Munich this weekend after Germany's federal prosecutor decided to take no action against him over a war-crimes complaint filed by a New York-based human rights group over the treatment of prisoners in Iraq.
