Apply the same logic to your assertion. There could be many legitimate reasons for Gov intelligence to control exit nodes without prosecuting every illegal activity.. Same as with local police not prosecuting every crime openly committed in nightlife districts of every major city.

Have you heard of parallel construction? LEOs use it to hide how they actually cracked the case and can get away with using inadmissible evidence.

I’m not sure this follows. Intelligence and federal police services routinely “manage” crime to various ends. Go read Tim Weiner’s Legacy of Ashes or Enemies for myriad examples.

Unless it’s the government doing the crime.
