Sounds like the writer wants to make cops teach a course in Constitutional law before questioning any suspect:
“The opinion only makes police tell suspects about a small subset of their constitutional rights, often by rote. Miranda does not require that the police make sure the accused understands how his or her liberties operate or what the consequences may be of talking to police anyway.
“Why do we allow this odd state of affairs?”
The police have a hundred ways around Miranda, and a hundred ways of lying to you and entrapping you.
Miranda means nothing nowadays. The protections embodied by Miranda have been whittled down to nothing.
Despite Miranda, they still know how to extract a false confession without leaving any marks. By the way, the verb “to extract” seems to be primarily used in the law enforcement and dental professions.
Ernesto Miranda, after being released from prison, was killed in a bar fight. Only one of the suspects was arrested. I presume that when the police arrested him, they read him his Miranda rights.
