FILE-In this March 22, 1959, file photo, Fidel Castro, Cuba's Prime Minister, salutes the crowd at labor rally supporting him in Havana. Causes across the political spectrum have long used distinctive salutes to identify themselves. When Anders Behring Breivik, the far-right suspect in the massacre of 77 people in Norway, pulled his right hand to his chest and then thrust his arm out with a clenched fist after an Oslo courtroom guard removed his handcuffs on Monday, April 16, 2012; it was hardly the first time such a salute has been flashed.
