I think that deciding whether a confession is valid or not is a matter for the jury, not for the police.
Edit: To be clear, when we're deciding whether or not a person accused of a crime has abrogated their legal protections, I think we should favor the accused, who the law has an obligation to consider innocent until they are proven otherwise in a court of law (or until they accept it as part of a plea deal, I guess). I don't want people to be disadvantaged because the police are more familiar with the proper legal terminology than they are.
Yeah. This is me too. It defeats the whole purpose of our protections. I personally know cause my family was reps and senators (who make the law) and military police and lawyers (who try the law) that you never ever EVER say anything to a cop short of your real name and address. Because it's just never gonna be an advantage to you without legal council. But your normal every day accuses drug dealer or escort isn't gonna know that usually. And they shouldn't be disadvantaged because of it.
MWC this might be the most reasonable and well-stated post I have ever seen from you and I just want to say that I wish you posted like this more often.
I agree completely with both you and MalcomMasher btw. ---
