Your milage may vary depending on local laws, etc.
Disclaimer: I don't live in Seattle any longer so the situation I am about to describe may have changed in recent years (but I doubt it).
Story: There's a 5-way intersection near the University of Washington campus. The city put up cameras and started collecting hundreds of thousands of dollars per year in fines. Problem: city ordinance stated something like any ticket resulting from a photo must come from a camera mounted at a 90 degree angle to the street. Notice the bit about it being a 5-way intersection? None of the roads came together at a 90 degree angle. Point was, the city continued to violate their own ordinance for years because that single intersection was a cash cow - the whole system was automated so the pictures were taken, cars identified, tickets mailed. THAT is why there is so much outrage about cameras in the US - it's the Man kicking us around.
