Answer: If you're referring to the jurors, no. We see the entirety of their deliberations. If you're referring to the prosecution or defense, that is unknown. Given, however, that none of the jurors brought up the question, it's likely there was at least a check of his clothes to verify he had a hole in his pocket.

Answer: We have to assume that there was a hole in his pocket; we don't see it, but if the jurors are talking about it as a given fact, then it is likely that they checked it during the trial. However, it does not prove anything. It is easy to rip a hole in a pocket to produce an alibi. Also, it does not lower the extreme unlikeliness that someone else with another but similar looking knife stepped into the boy's apartment at around the same time he lost it. "One in a million," one juror said, and it was not really disputed. No. 8 gave his typical but meaningless "it is possible." Still, they went for an acquittal with these high odds against the boy.
