This needs to be established at every interaction with cops. I always hear the cops say that even though they check me out, their partners in the other patrol car might still harass me. Each cop is individually different. They generally work by themselves and supervise themselves out in the public. Their main source of communication with their co-workers is through radio. Some nights they may not even meet face-to-face on a shift.
You know what’s funny is that every cop is required to read the Miranda Rights verbatim. They are not allowed to speak those rights from memory to people, or it can get thrown out of court. That’s why it’s called being “read your rights” and not “recited your rights”.
