To answer this question, it’s important to consider how Miranda warnings are used in the real world. First of all, officers are allowed to stop, detain and question a person if they have a reasonable suspicion that the person is engaged in committing a crime.  For example, if a person is driving drunk and provides a breath sample that is over the legal limit, they can legally be charged, arrested and jailed without ever hearing a Miranda warning. Police only have to read a person their rights if they plan to interrogate them.
