So what you are saying is that it is false to say, in the U.S., that someone has the right to remain silent or that they have the right to counsel.You might want to my posts before quoting and responding. Laws can be changed. Rights cannot be.
Please name one "right" that people have, according to YOUR definition, that cannot (and, indeed, has not sometime/somewhere) been taken away because a law was changed. About the only one I can think of is the right to think whatever you want within your own mind as long as you don't express it in any way, shape, or form. Though there is a push to effectively make certain types of thought illegal.
