Seriously, dude, they have you on the terrorism watchlist ? They make reference to this ? That is even scarier than Houghson's creepy smile.
Lots of possibilities about this. The terrorism watch list comes from the Feds and has levels.
The state also has a list and can be for a variety of things.
Then every locality I know has their own little list they take from contact interviews, etc. Years ago an 80 something year old woman yanked the badge off a henrico cops shirt. She was put on the local dangerous person list
I daresay we are all on one or more lists.
