A fleeing bank robber ran into a school and took the principal hostage at gunpoint. The police, who had received a detailed description of the clothing the robber was wearing, surrounded the school and demanded that the robber come out with his hands up. When it began to get dark, the robber ordered the principal to undress, and the robber switched clothing with the principal. He tied the principal's hands to his side and pushed the principal out the door first. Seeing that the first person out of the door did not emerge with hands up and that the person was wearing clothing the robber was described as wearing, a police sharpshooter shot and killed the principal. The robber was captured and put on trial for the murder of the principal. Should the jury find the robber guilty?
