Wendy, а cаshier аt The Cоffee Hоuse in Pearlridge, was rоbbed at gunpoint by a man who demanded that she give him all the money she had in her cash register. Wendy complied and the robber fled with approximately $300.00 in cash. About an hour after the robbery, Wendy gave a description of the robber to the police. Two hours after the robbery, Wendy met with an artist for the Honolulu Police Department, who drew a composite sketch of the robbery suspect based on Wendy’s description. A week later, Wendy picked appellant’s photograph from a photographic array of about twenty-five to thirty pictures. At trial, Wendy confirmed her prior identifications and pointed out the appellant as the person who robbed her. Appellant presented an alibi defense through witnesses who testified that he was with them on the day in question. The jury found the appellant guilty. Appellant appealed, arguing that the trial judge erred in admitting the police sketch artist’s composite sketch. What is the strongest basis for appellant’s argument?
