Why so many armed guards and police?
Though it may come as a surprise to you on your first visit to some countries, there are many establishments that have armed guards and police may carry large rifle type guns. This does not mean it is a high crime area whatsoever, it is just the way things are. It is hard to convince someone that has not experience this to be a fact, but it simply is the way it is, no more no less. For example, one would assume the USA is constantly at war, from the fact of so many nuclear bombs they have, but the fact remains they have only used them twice in fifty years. The same is here: many guns, but they have rarely been used.
