It's not like that everywhere. I live in New Zealand, and have chatted with police at length even when they are there to get us to move along (as teenagers skating and bmxing). Yes, there are shameful episodes (Louise Nicholas, accidental shooting on Auckland motorway, Arthur Allan Thomas, et al), however by and large, it seems to mostly be the older generation of police that are/were involved. I have no fear of police here and I don't know anyone that does.
