“It seems to me to be a very low hurdle for police.”
You mean like the reading of the Miranda rights and the confirmation that the police get from the culprit? I mean he was told - keep your mouth shut or else!
He CHOSE “or else”! No law is going to fix that!
That could have well been weeks or months before; in addition, the suspect--who was interrogated and given Miranda--is now a defendant, who has been arraigned and assigned a lawyer. He may well not know that his lawyer is entitled to be present at these interrogations, or that he's entitled anything else than to be assigned an attorney, as he was at the arraignment.
Anyhow, I think it's bad policy but it appears, at least for the time being, I'm on the losing end of this argument. It troubles me, however, to see such a low-cost rule that helps protect the rights of the accused jettisoned for little reason.
