I have only flown through Seattle and never really spent more than about 6 hours in the city proper (outside the airport), yet I was creeped out by their police as early as 2000 - long before the stories of abuse came out. Here's why:
I'm coming off my flight in Seattle for the first time and waiting for another, when all of a sudden, interrupting the normal announcements, the speakers across the airport are blaring out "DO NOT WORRY, CITIZENS! THE POLICE AND FIRE DEPARTMENTS ARE HERE TO ASSIST YOU." This was over a year before 9/11 so it never occurred to me that some sort of terrorist attack had happened, and as far as I knew, the police in Seattle had done nothing notable to rile up the citizenry. Yet the fact that they felt the need to reassure me every 10 minutes (for 3 hours...) that they're here to help me was the weirdest thing ever.
That is all.
