[Skyrim] Why is some random prisoner that escaped Helgen and sided with the opposite faction allowed to walk up to The Jarl or Solitude or Ulfric Stormcloak without being forced to Kneel or be arrested.

If you side with the Stormcloaks at the beginning you can somehow take a carriage to Solitude, walk up to the Jarl of the Capital of Skyrim and they are totally cool with that. Why?

He wasn't on their list of prisoners, Helgen Keep was destroyed and few Imperials escaped. Skyrim has no mobile internet, unless the Last Dragonborn actually tells people no-one would know and as he wasn't actually a documented convicted person it's not clear that formal Imperial law would allow his arrest in more civilised environments than an ad hoc battlefield execution.
