No, that's the "homing system" side of this analogy. GP is talking about some sort of poison (chemo), but I don't know which one or what the paranoia is about.
Yeah there's stuff that will get you on lists especially since 9/11. But some of them have been restricted since before that, though de facto unenforceable. Today there is the ability to ingest huge volumes of data. I just don't want to deal with the pain in the ass even if I'm found innocent.
