Visitors to Egypt are surprised by the vast numbers of armed police and army everywhere. It isn't nearly as alarming as they appear. Every young man in Egypt unless he is supporting his family or is an only son or his mother is a foreigner must put in two years compulsory military duty that may be fulfilled with either the police or the army. Most of these young men stand about directing traffic and the local wisdom is never to ask directions from any of them since they probably have no idea where they are. Most of the guns have no bullets, by the way.
