Oh, I see. It seemed very different with our country policemen detective methods. Though our police need evidences for accuring suspect, 'imaginary' evidences is enough. For this case, the cop and the Turk are dead, only Mike is still alive at the murder scene. And only these 3 guys had a dinner together. No more trajectory test, No more fingerprint analysis for our country policemen, there can be no doubt that Mike is murder. If he didnt admit it, OK, our policemen have "methods" to let he talk.
