Mexico beefs up prison to deter another Guzman escape

A military tank is stationed outside Mexican drug lord Joaquin "El Chapo" Guzman's prison. Authorities have taken extraordinary steps to prevent Guzman from escaping from the Altiplano prison for a second time while they seek to extradite him to the United States. Guzman was returned to the prison hours after he was recaptured in a deadly marine raid in his home state of Sinaloa on Friday.
