The latest incarnation of anti-war protest is enough to make you queasy. According to San Francisco’s Bay City News, some peace activists have decided that the best way to protest American foreign policy is to lose their lunches on the steps of the federal building.

The formal vomit in included approximately 300 protestors prepared to heave on the sidewalks as a demonstration that war in Iraq made them sick. They were kept in line by scores of officers from the Federal Protective Service and the San Francisco Police Department.
