I listen to a security researchers podcast, and they mentioned Tor exit nodes being set up by governments to figure out where messages were coming from and track down individuals

There was also this article I found where the FBI exploited a vulnerability to expose the IP of a wanted individual

Tor has been used to track and arrest people before. It isn’t 100% guaranteed like being offline is.
