Murder staying really still after killing

I'd be surprised if nobody that uses youtube had heard of jcs, the channel that started the trend - the youtube algorithm basically put his videos in everyones' recommendations before them getting demonitized for their content. Many others have followed and managed to avoid demonitization, but most of them showing the reid technique, the use of the alternate question etc, to be successful. But the case of Stephen McDaniel is different in that he says nothing other than yes, no, or I don't know. The Georgia detectives are also an almost southern stereotype and aren't that competent - can't follow the reid technique, letting their emotions jeopardise the interrogation, etc. At one point a detective stares him down, only to be stared back at with such intensity that he breaks eye contact. I guess I can't expect many people to watch a one hour video bases on this but it's probably the most unusual interrogation ever released to the public
