Because of a series of high profile espionage arrests, the press dubbed 1985 “the Year of the Spy.”That spring, the John Walker Spy Ring—John Walker, Jerry Whitworth, Arthur Walker, and Michael Walker—was arrested for passing classified material to the Soviet Union. On November 21, Navy intelligence analyst Jonathan Jay Pollard was arrested for spying for Israel. On November 23, Larry Wu-Tai Chin, a former CIA analyst, was arrested on charges of spying for the People’s Republic of China since 1952.
