As the bank robber lays wounded on the ground and debating whether to go for his gun, Callahan says to him, "Ah, ah. I know what you're thinking. Did he fire 5 shots or 6?" After the robber tells Callahan that "...I gots to know." Callahan points the gun at him and "fires" a blank, implying that he fired all 6 shots. If you count Callahan's shots from his first, he only fires four! Whre are the other two or did he only have 4 to begin with?
