I've often wondered if speeding tickets and the like are the reason for the general decline in positive opinion of the police. (I've done no research on this whatsoever–anyone have any pointers to interesting materials?) But it seems that the police were, once upon a time, the friendly man on the corner keeping you safe, and now they are the guy with flashing lights who will pull you over. Somehow I expect that change in opinion has cost the police far more than they realize. (Of course, past positive perception of police could be a myth, too: I've not been around long enough to know.)
