I am looking forward to reading this book:
Hazem Kandil’s “Soldiers, Spies and Statesmen: Egypt’s Road to Revolt”
"Today, Egypt has the highest per-capita security personnel in the world. There are 25 security personnel to 1000 civilians; 2.5 percent of the society works in security. At its height, the KGB in Russia did not employ more than 150,000 servicemen. Egypt in 2012 had about 2 million."
