Lee Harvey Oswald was shot November 24th 1963. Do you believe he was JFK's real in?

I believe that Oswald fired the fatal shots. There have been a number of reenactments and tests that show it is very possible for Oswald to have fired the shot that hit Kennedy and Connally. However, I don't think he was alone that day and that other shooters were in the area. And, I believe that the mob had something to do with JFK's death -- JFK had taken Mob help to win the Presidency and then, along with his brother AG Robert Kennedy, started prosecuting the Mob once in office. Further, I believe that Jack Ruby was ordered to make sure Oswald remained quiet.
