For those like me who have not attached a front license plate, Seattle Police are out in force on 4th Ave S, issuing tickets for anything and everything, including not mounting your front plate. They just issued me such a ticket, despite having the plate and mounting hardware there to show them. Another officer issuing a ticket nearby stated that due to three years of pressure from the City of Seattle to issue more tickets, they now have a "quota" (his word, which police usually avoid admitting), and that SoDo is the quickest place for them to reach it. (The officer was munching on a snack of some kind both during the ticket and 15 minutes later when I had to locate him again to re-write part of the ticket that I could not read in the carbon copy, which he blamed on inferior carbon paper that the City gives them.) So, when driving near the Seattle Service Center or between there and Costco, beware.
