To discredit Chambliss's claims that Rowe had committed the bombing, prosecuting attorney William Baxley introduced two law enforcement officers to testify as to Chambliss's inconsistent claims of innocence. The first of these witnesses was Tom Cook, a retired Birmingham police officer, who testified on November 15 as to a conversation he had had with Chambliss in 1975. Cook testified that Chambliss had acknowledged his guilt regarding his 1963 arrest for possession of dynamite, but that he (Chambliss) was insistent he had given the dynamite to Rowe before the bombing. Following Cook's testimony, Baxley introduced police sergeant Ernie Cantrell. He testified that Chambliss had visited his headquarters in 1976 and that he had attempted to affix the blame for the 16th Street Baptist Church bombing upon an altogether different member of the KKK. Cantrell also stated that Chambliss had boasted of his knowledge of how to construct a "drip-method bomb" using a fishing float and a leaking bucket of water. (Upon cross-examination by defense attorney Art Hanes Jr., Cantrell conceded that Chambliss had emphatically denied bombing the church.)
