I think of cops like a bear in the woods (except less cuddly and interesting). They are something dangerous to be avoided. I steer clear of them at all costs. If I see them up ahead on the road, I take a detour. If I'm lost, I stay lost rather than ask them for directions. I want no interaction with them at all, if it can be helped (in a professional capacity, at least... if I had the opportunity to engage them in meaningful conversation off-duty, I would do so in an effort to contribute to their rehabilitation; though I don't generally get the sense they're up for deep conversations concerning moral imperatives and the like).
