Unchecked, the tourist will climb over the fence and come right into your house to take pictures of you in your habitat. Cities mindful of tourists have built elaborate "tourist traps" which, luckily, work. Tourists are kept confined to these, and few escape. There is, of course, the type known as the "intrepid tourist." This one has to be watched carefully or he can become most annoying. Little wonder these are so often the target of terrorists. If there is an aspect of benign terror about the tourist, there is also a great deal of tourist in the terrorist. Terrorists travel with only one thing in mind, just like the tourist, and the specifics of places escape them both. Terrorists travel for the purpose of shooting unsuspecting foreigners, just as tourists travel for the purpose of shooting them with a camera.
