On May 21, 2002, both prosecution and defense attorneys delivered their closing arguments to the jury. In his closing argument for the prosecution, Don Cochran said the victims' "Youth Sunday never happened ... because it was destroyed by this defendant's hate." Cochran outlined Cherry's extensive record of racial violence dating back to the 1950s, and noted that he had experience and training in constructing and installing bombs from his service as a Marine demolition expert. Cochran also reminded the jury of a secretly obtained FBI recording, which had earlier been introduced into evidence, in which Cherry had told his first wife, Jean, that he and other Klansmen had constructed the bomb within the premises of business the Friday before the bombing. He said that Cherry had signed an affidavit in the presence of the FBI on October 9, 1963, confirming that he, Chambliss, and Blanton were at these premises on this date.
