House Select Committee on Assassinations. An investigating committee set up by the US House of Representatives, whose conclusions are totally opposite to the
Warren Commission ones.
This commission concluded there was a 'high probability' that, along with
Lee Harvey Oswald, a second gunman shot at
John F. Kennedy on November 22, 1963. The
HSCA thought that JFK was assassinated as a result of a conspiracy, though it proved unable to identify its members.
