well its pretty clear from his actions that he was.
Actually, that's not QUITE true. He may have been registering his dissatisfaction with the way the investigation was proceeding. He was within his rights to do so. HOWEVER, it was entirely down to the police if they allowed themselves to be influenced by anything he said. One reads statements such as "He/she made me do it". This is rarely true. We usually have a choice. So whatever it was you imagine he may have been responsible for 'making' the police do, it would have been their choice.
