Some Chicago fire hydrants have special devices to keep people from turning them on. This one in this episode has one of of those devises and Ronnie had no problem getting through the lock without a key. Writers for the Chi need to go to Chicago and talk to residents or find writers from Chicago to write the story of their city. The current writers are not. When I saw The Wire, even though that was about Baltimore, it still felt like things that happened in Chicago. The Chi is missing that feeling and it's supposed to be about Chicago.
