I devoured this book in a single weekend. It is an easy and entertaining read. The book is repetitive and at some points the author delves too far into his analysis without providing additional insight. There are some gems in it, though.
The security concerns it brings up are eye opening. Every single system has vulnerabilities. Most are easier to find than you might think.
I find the orthogonal way that burglars think is useful to defeating what we at Praxis call “the permission mindset” and also useful to approaching new problems. Perspective changes, such as viewing LA by air like the LAPD Air Support Division, also provides useful new ways to approach problems.
