In a news article in CNN 23 November, Juliette Kayyem (National Security Analyst), discusses whether it is a good idea to close down a city or not when expecting a terror attack. Brussels has now been shut down for three days. Economically of course it is a disaster, but psychologically it is even worse because the population in a whole city is affected. The question is whether it will be possible to live normal lives when the city is opened up again? Even more important, has not the IS achieved one of their main goals when they manage to close down a capital city? A city that is also the home of the headquarters of the European Uninon, and a major center of economic affairs in Europe? As Kayyem says in her article, "Thus, shutting down a city is a tactic that should only be used in the rarest of circumstances, based on criteria that are known to the public and that are understood by those who implement them."(http://edition.cnn.com/2015/11/22/opinions/kayyem-belgium-lockdown/index.html?eref=rss_world)Image retrieved from: http://images.scribblelive.com/2015/11/22/9f1e4653-9013-4c2e-a3a4-abcd09777e7b.jpg
