Mexico's Felipe Calderon gives final State of the Nation address
Calderon's six-year presidential term ends this year, and Mexican law prohibits him from running again.
In his State of the Nation speech, Calderon said he expanded and cleaned up Mexico's police force and created more than 2 million jobs -- twice as many as his predecessor, Vicente Fox.
Calderon did acknowledge that mistakes have been made in the government's fight against drug trafficking and organized crime but said the effort had helped keep criminals from taking control of the country.
Calderon will leave office on December 1st. He'll be succeeded by president-elect Enrique Peña Nieto.
