Query: Not terribly relevant except in a fantasy world.

This is a mildly interesting book about the methods the author uses to keep himself safe in the Holy Land. You will not learn much that is of practical value in the USA. I'm not even sure I believe that he goes always armed with several pistols and knives. If you follow his recommendations you would find yourself under arrest for a variety of felonies in most US jurisdictions. Other than those caveats, it's a decent book!
