The article about OPSEC with utility workers reminded me of some of the deterrents listed in the book, Secrets of a Superthief by John MacLean. The author was a very successful thief until he violated one of his own rules and was caught. In his book he details what vulnerabilities he looked for in a victim, and how he performed his thefts. Chances are you have taken precautions but reading his book will real to you the
chinks in your armor. The book leaves you feeling vulnerable, and is a wake-up call to fortifying your defenses against theft or unlawful entry by undesirables.
The book is out of print and copies are snatched-up as soon as they become available on the secondary market. I highly recommend the book. – Rick B.
