Question: In what state did McAtee play professional hockey in the NHL? Passage:Norman Joseph McAtee (June 28, 1921 – August 25, 2010) was a professional ice hockey player who played 13 games in the National Hockey League with the Boston Bruins. Born in Stratford, Ontario, he and his brother Jud played together in junior ice hockey with the Oshawa Generals during the years when the Generals dominated the Ontario Hockey League, winning championships with them in 1938–39. 1939–40 and 1940–41. At the end of the 1941 season, Norm joined his brother by signing as a free agent with the Detroit Red Wings in the NHL. However, beginning in 1942 and lasting throughout World War II, Norm became a flying officer in the Royal Canadian Air Force. After his discharge in 1945, he teamed with his brother in the Red Wings farm system before the two of them were traded to the Chicago Blackhawks for Doug McCaig in December 1945. Just over a month later, Chicago traded him to Boston for Bill Jennings, and Norm joined the Bruins for 13 games, recording one assist. After that, he finished his career in the minor leagues, ending as player-coach with the Troy Bruins in Troy, Ohio from 1951 to 1954.

Question: When was the author of JFK and the Unspeakable born? Passage:Jim Garrison said anti-Communist and anti-Castro extremists in the CIA plotted the assassination of Kennedy to maintain tension with the Soviet Union and Cuba, and to prevent a United States withdrawal from Vietnam. James Douglass wrote in JFK and the Unspeakable that the CIA, acting upon the orders of conspirators with the "military industrial complex", killed Kennedy and in the process set up Lee Harvey Oswald as a patsy. Like Garrison, Douglass stated that Kennedy was killed because he was turning away from the Cold War and pursuing paths of nuclear disarmament, rapprochement with Fidel Castro, and withdrawal from the war in Vietnam. Mark Lane — author of Rush to Judgment and Plausible Denial and the attorney who defended Liberty Lobby against a defamation suit brought by former CIA agent E. Howard Hunt — has been described as a leading proponent of the theory that the CIA was responsible for the assassination of Kennedy. Others who believe the CIA was involved include authors Anthony Summers and John M. Newman.

Question: What was Jimmy Page's net worth the year Klausner presided over United States v. Ancheta? Passage:In 2006, Klausner presided over United States v. Ancheta, the federal prosecution of Jeanson James Ancheta of Downey, California, the first botnet-related prosecution in U.S history. Following Ancheta's guilty plea, Klausner sentenced Ancheta to 57 months in prison for various botnet-related crimes. In 2016, Klausner presided over a copyright case filed by the estate of Spirit guitarist Randy Wolfe against Led Zeppelin founders Robert Plant and Jimmy Page. The estate of Wolfe alleged that Wolfe was entitled to a writing credit for the song "Stairway to Heaven"; Klausner ruled in April 2016 that a jury could find "substantial similarity" between the elements of the two songs. In another copyright case arising from the Star Trek fan film Prelude to Axanar, Klausner rejected various motions by both parties in January 2017, setting the stage for a civil trial on the matter to go forward. The parties settled the suit. In August 2017, Klausner dismissed a class-action lawsuit filed by boxing fans who contended that the 2015 Floyd Mayweather Jr. vs. Manny Pacquiao boxing match was deceptively marketed because Pacquiao failed to disclose a shoulder injury that affected his performance. Klausner ruled that fans of sporting events have no right to have the event meet their expectations for excitement. In October 2017, Klausner ruled in favor of the plaintiff Coachella Music Festival in a lawsuit against the fledgling "Filmchella" film festival, finding that the names were likely to cause consumer confusion.
