Question: Suspect X was arrested by the police in downtown San Francisco. He was charged with robbery. He asked for a lawyer and was given a public defender. A week later, X was made to appear in a police lineup. He refused, saying that he would do so only if his lawyer was present during the lineup. He further objected to the lineup on the grounds that it would violate his constitutional right to due process and protection against self-incrimination and that it was also a violation of his Fourth Amendment right against unreasonable searches and seizures. You are the judge in the case. Will you uphold or reject X's allegations? Analyze each allegation and give reasons for your decision.
