While chatting with the "person of interest", detectives can witness a guilty outburst. At that point, they can THEN make an arrest, and THEN inform the subject of Miranda.
Cases won by prosecutors are today being appealed citing Miranda—going back decades. That the NYTs writes glowingly of Miranda "Rights" should be a clue. "Police are chipping away at Miranda"
American Spectator:
"After the Supreme Court handed down Miranda, hundreds of criminals had their convictions overturned because of retroactive application. Many were admitted murderers. Thousands of other confessions have since been thrown out before they ever reached the courtroom.
All this turned loose a lot of potentially dangerous people."
It is best to never talk to the police.
With that, you will never knowingly, unknowingly, intentionally or unintentionally incriminate yourself for a crime that you may have committed or a crime that you had nothing to do with.
I have never spoken to a person that was arrested and not read their Miranda Rights or made aware of their rights under Miranda.
