No where in the 5th Amendment does it say that once you start talking, then you "waive" your rights.
It plainly says that a person cannot be compelled to testify against themselves. Period. No caveat, no kings X, no dipshit judges opinion.
This is one of our Bill of Rights. You can waive a privilege, because that is something granted to you. But a "right'. That is ludicrous.
What part of "nor shall be compelled' do these people not understand.
