(How is it the Ice Nation knows of the Polis tunnels and can so easily smuggle in knives and bribe guards?)

Did they writers state elsewhere that Lexa established Polis or she just moved in to the capital. If she just took up residence as the reigning PM - I'm sure past Commanders have been from the Ice nation. If she did create Polis - the coalition would've given IN clan free trade within the city that they probably exploited for their own needs for a rainy day.
