A man buys slippers showing pictures of former Egyptian President Hosni Mubarak, his son Gamal and former Interior Minister Habib el-Adli with nooses, at the police academy where they are on trial in Cairo January 4, 2012. Egyptian prosecutors seeking a conviction against Mubarak on charges of ordering the killing of protesters took the stand for the first time on Tuesday, criticising his political record in a session brought to an abrupt end by the presiding judge.
