Tourists have their lives and Citizens have their lives, and the two do not mix. They may both use a few of the same entertainment buildings, but otherwise they go their own ways.
Tourists arrive and stay for 600 to 750 days and then they leave. They leave when they walk into the Port or Airport Terminal buildings; the player has no gameplay way of stopping them.
The player can not assassinate\eliminate tourists. The 'Spring Break' tourists may riot, but the player may not arrest them or any other tourist.
Well there aren't any secret police and that is a bummer ...
What did all those early players want, an egg in their beers? My word!! It's hard to understand how any "on map" NPC 'spooks' could provide a more complete dossier on each citizen and tourist than is already available by clicking on one and looking at the seven information panels. The spooks are "subsummed" into the background. O.K. - there isn't any way to do a secret 'disappearance' - but is there ever a way to do that? In a small country, everyone knows who the secret police are -- except perhaps the secret police themselves who often aren't the brightest bulbs in the string. El Presidente is the only one smart enough to put it all together. Or else the whole game could run without a player, eh?
