selling merchandise in a city park without a permit; Dealey Plaza is under the control of Dallas' Parks and Recreation Department. In December 2010, the case was dismissed by a judge who agreed with Groden's defense that Dealey Plaza was not a city park and that the city neither offers nor requires permits to sell merchandise in parks; the city appealed. Groden, whose lawyers said that he was arrested without probable cause and that his right to free speech was violated in the process, sued the City of Dallas for $900,000 in "mental anguish," $100,000 for damages to his reputation, and $1,000 for merchandise that was confiscated. In addition he sued certain police officers for violation of his constitutional rights. The City of Dallas filed a motion to dismiss which the court subsequently granted on the basis that Groden failed to adequately plead his case against the city. The suit against one of the police officers proceeded to trial. On June 12, 2014, jurors deliberated for an hour and returned with a verdict stating that the arresting officer's actions did not violate Groden's constitutional rights. Groden's attorney claimed that the jury indicated they did not want to punish the officer for a crime committed by the city and asked why the city was not a defendant. In October 2014, Groden filed a motion in the United States District Court for the Northern District of Texas requesting for the dismissal order be vacated and he be granted a new trial against both the City of Dallas and the police officer. The Court denied the motion by stating that Groden failed to remedy the early deficiencies in his claims against the City. Groden successfully appealed the dismissal of his lawsuit against the City of Dallas. In June 2016, the United States Fifth Circuit Court of Appeals reversed the District Court's dismissal and remanded the case to continue against the city. Groden's Monell claim was allowed to be pursued. The Appeals Court permitted the police officer's ruling to stand. Books (with F. Peter Model) JFK : The Case For Conspiracy, Manor Books, 1977.
