Fifty years after JFK assassination, conspiracy theories live on

The 50th anniversary of the assassination of President Kennedy also marks 50 years of conspiracy theorists trying to sell an array of alternative explanations for JFK’s murder. Over all the long years since Nov. 22, 1963, conspiracy theorists have fingered more than 40 different groups, 80 different assassins and in excess of 200 co-conspirators.
 Of course, not all of those accusations can be true.
