Thousands of farmers, workers and agricultural laborers march through New Delhi streets demanding better wages, more jobs, better prices for farm produce and an end to privatization of state-run companies.

Robert Kennedy aide Paul Schrade holds an evidence photo of gunman Sirhan Sirhan's revolver with the eight expended shell casings found in the chamber, and the Weisel, Goldstein, and Kennedy bullets, at his home in Los Angeles.

Schrade woke up the next day and found out the Democratic presidential candidate was dead. Today, Schrade believes the Los Angeles Police botched the case and failed to investigate possible leads about a second gunman. (AP Photo/Damian Dovarganes)
