Its because the PAW patrol is not a government subdivision and instead they’re a private group of mercenaries, therefore they had no gain in involving themselves with the entire situation. So they instead focused on a ”hit and run” on an opposing mafia crime boss, but never got caught. Also, it would actually put them at a disadvantage with the costs of travel due to them having a low budget and the potential for things to get messy, and might end up in a court, so they decided not to involve themselves in the situation.
