I can. I live one county north of King county and have seen how the King county sheriff deputies like to operate. For any given call there will always be at least two squad cars, and a K-9 unit SUV with extra weapons.
Because apparently a heavily developed, high-economic productivity area is a warzone 
IIRC King county also got a PATRIOT Act grant for a fleet of hovercraft that they don’t have any use for, because boats exist.
Maybe they’d be useful in Snohomish county, but I don’t really think so.
Killing anyone needs to be directly expensive to the officer pulling the trigger. It’s gotta be worth it to them. Right now we don’t prosecute wanton acts of the police murdering people, and it costs them nothing. I’d say it’s better to make any shooting cost cop a lot of money, than to both not prosecute them and give them no disincentive.
