This line of questioning is especially effective if the suspect is guilty. Oh shit, I better go in and talk to them or they'll think I did it. The thing is, they are interrogating you, often for hours on end, because they already believe you could be the guy they're looking for.
It seems likely it is better to close your mouth and let them think you're guilty, rather than open it and remove all doubt.
