I believe the objection people have is to ever being put in a situation where you have to explain yourself anyways, even if you're innocent. "Just be polite to policeman, calmly explain the situation and he won't hurt you." The optimal strategy is to avoid interaction/scrutiny whenever possible because every interaction adds a non-zero chance that someone with a quota/chip on their shoulder/bad day is about to ruin you.
