John F. Kennedy last words were:
"No, you certainly can't."
This was said in reply to Nellie Connally, wife of Governor John Connelly when she commented, "You certainly can’t say that the people of Dallas haven’t given you a nice welcome, Mr. President."
John F. Kennedy was born on May 29, 1917 in Brookline, Massachusetts. He served both the U.S. House of Representatives and U.S. Senate before becoming the 35th president in 1961. JFK got assassinated on November 22, 1963.
It is not the famous film you know from the Kennedy assassination, but the six seconds Orville Nix captured could be the most important now. Nix's film shows the final bullet striking the president.
