Indian social activist Anna Hazare (C) waves as he addresses supporters after walking from Tihar Jail in New Delhi on August 19, 2011. Indian activist Anna Hazare has left jail to start a two-week public fast likely to fuel an eruption of angry protests over corruption that has left the government stumbling for a response. Thousands of frenzied, flag-waving supporters cheered the diminutive 74-year-old as he walked from the gates of Delhi's Tihar jail -- his de-facto campaign headquarters since he was taken into police custody three days ago.
