One of the first questions from a reporter after his capture was if he had been marandized and it has come up several times since...If you don't think one or more lawyers represnting him isn't going to make that an issue you are way too naive.
I’m afraid I don’t understand your concerns. The entire point of the Miranda warning is to make sure statements made by the accused to cops will be admissible as evidence in court.
I have never seen any claim by anyone that evidence acquired by other means is inadmissible if the Miranda warning is not given. If you have proof of this, I’d sure like to see it.
