One of the key witnesses to testify on behalf of the prosecution was the Reverend Elizabeth Cobbs, Chambliss's niece. Reverend Cobbs stated that her uncle had repeatedly informed her he had been engaged in what he referred to as a "one-man battle" against blacks since the 1940s. Moreover, Cobbs testified on November 16 that, on the day before the bombing, Chambliss had told her that he had in his possession enough dynamite to "flatten half of Birmingham". Cobbs also testified that approximately one week after the bombing, she had observed Chambliss watching a news article relating to the four girls killed in the bombing. According to Cobbs, Chambliss had said: "It bomb wasn't meant to hurt anybody ... it didn't go off when it was supposed to." Another witness to testify was William Jackson, who testified as to his joining the KKK in 1963 and becoming acquainted with Chambliss shortly thereafter. Jackson testified that Chambliss had expressed frustration that the Klan was "dragging its feet" on the issue of racial integration, and said he was eager to form a splinter group more dedicated to resistance.
