Imagine that the first sentence of a contemporary opinion by the California Supreme Court opinion begins with the sentence: "We granted review to decide whether to overrule a 1971 pro-Miranda decision of this Court." Which is essentially what the first sentence of this opinion says.
In light of that sentence, do you have any doubt whatsoever what the answer's going to be?
I thought not.
2010 ain't 1971. Particularly where Miranda's concerned.
