The Art of Executive Protection
This book gets high marks for authoritativeness and relevance.    Robert Oatman is a highly regarded leader in executive protection, and   the importance of that field becomes more obvious every day.  Gianni   Versace and Princess Diana are not the only people who could have   benefited from better protection.  Business travelers, people who are   relatively well-off financially, and people who are recognizable to   potential wrongdoers . . . all can gain from learning about the   advantages of executive protection.  Anyone considering a career in   providing executive protection should also read the book.
