I'm Libertarian, anything else is progressive and unacceptable to me.
No, you're a tinfoil hat wearing moonbat.
All this says is that being mirandized once does not give you lifetime Miranda immunity. Once you have been read your rights, you can subsequently waive those rights and have your statements used against you. If you were mirandized for a burgulary charge, but then they question later you on a rape charge, should the first Miranda still apply? Hell no. Like the Justice said - too many career criminals in this country. All this does is clarify that common sense position.
This is not giving the police any more power than they had before. it is just clarifying how long a single Miranda warning can remain in effect. Again - the government cannot FORCE you to open your damn mouth. They can, however, wait two weeks and question you again. The shot clock resets. If you are stupid enough to confess the second time they question you, well, aren't you a moron?
And aren't I a moron for arguing with you...
