November 6 marks the 29th anniversary of the M-19 guerrilla organization's storming of the Colombian Palace of Justice. In the resulting heavy handed military response, dozens were killed, including half of the country's Supreme Court justices and many of the 30 M-19 militants involved in the action plus some judicial workers disappeared and their whereabouts still remain a mystery. Relatives of those disappeared demand justice three decades later. Charles Parkinson reports from Bogota. teleSUR
