Query: Useful handbook

I bought this because I already owned the superb Boston's Gun Bible which is stuffed full of mostly irreproachable tips on weapons ownership.It's hard to critique this book, however. In fact, I hope I never need to know any of this stuff. I'm betting it will come in handy and that I will regret not having fully assimilated its concepts. As I'm a geek and not exactly a people person, I would have considerable trouble finessing some of the social situations (i.e.: interaction with government employees) discussed in here.Looks good, however. The lack of the fifth star is a) because I can't judge the quality and b) I probably can't do some of what is suggested.
