If you want to know what really happened at the trial, you should read “The Trial of the Chicago 7: The Official Transcript” by Mark Levine and Danny Greenberg, which has all the major testimony and confrontations in the trial — verbatim! — from the actual transcript. It’s the 50th anniversary edition of “The Tales of Hoffman” which came out ten days after the trial ended in 1970 and has more of the testimony, and from more witnesses, than any other book around.
