Instead mention your Sixth Amendment right to a lawyer, and tell the police that you want a lawyer. Is that honest? Not entirely, because it sounds like you are implying that you might be willing to talk to them after a lawyer shows up, and of course that is not true, and your lawyer will not agree to that. But a little dishonesty is a small price to pay to defend your freedom and your constitutional rights, especially when dealing with police officers who will lie to you until the sun goes down.
