The only rational behavior when dealing with law enforcement of any sort is the same way you'd treat any other dangerous, and possibly violent wild animal - move slowly, don't be the least bit threatening. Any random cop does have the ability to ruin your day, or worse, and there's jack and squat you can do about it until after the fact, if then. That's not even hyperbole - it's rational, objective fact.
