How many mock trials of this case have you seen?
Many details that would have been highly contested in a normal trial, or would likely not be admissible, were agreed upon by stipulation between the lawyers at the mock trial. The witness testimony was also limited to just a few questions, where such testimony could have gone on for days during a real trial. And the chances of finding a truly impartial jury after so many years of media attention for the case were not great.
Yeah, gone on and on forever like you blowhard Oswald arse-kissers, when in fact Oswald killed Tippit in front of witnesses and Rosetta-stoned Kennedy.
Re the mock trial
Wikipedia:
Bugliosi based much of the book on his preparation for a mock trial of Lee Harvey Oswald staged by British television, in which he acted as the prosecutor of Oswald. The mock trial involved an actual US judge and US citizens acting as jurors, and Oswald was defended by prominent trial lawyer Gerry Spence. Bugliosi obtained a verdict of "guilty." He wrote in the Introduction to his book:
'My professional interest in the Kennedy assassination dates back to March 1986 when I was approached by a British production company, London Weekend Television (LWT) to "prosecute" Lee Harvey Oswald as the alleged assassin of President Kennedy in a proposed twenty-one hour television trial to be shown in England and several other countries, including the United States. I immediately had misgivings. Up to then, I had consistently turned down offers to appear on television in artificial courtroom settings. But when I heard more of what LWT was contemplating, my misgivings quickly dissolved. Although this could not be the real trial of Oswald...LWT, working with a large budget, had conceived and was putting together the closest thing to a real trial of Oswald that there would likely ever be, the trial in London being the only "prosecution" of Oswald ever conducted with the real witnesses in the Kennedy assassination. Through painstaking and dogged effort, LWT had managed to locate and persuade most of these original key lay witnesses, many of whom had refused to even talk to the media for years, to testify...There would be absolutely no script...and no actors would be used.'
