although those are good books, i prefer more current texts. these are a few of my favorites.
1.) LIESPOTTING, a book on detecting when people are lying to you
2.) HOW TO DISAPPEAR, a which is great if you ever need to hide
3.) SURVEILLANCE COUNTERMEASURES, how to tell when your being watched or followed
4.) COUNTERING HOSTILE SURVEILLANCE, techniques on how to deal with and evade anyone
5.) MAKING & BREAKING CODES: CRYPTOLOGY, about how to encrypt messages so only you and those in the know can read them.
you can find these on amazon ,but WARNING....learning these subjects will make you extremely aware of your surroundings and overthinking situations becomes a habit, but these subjects apply perfectly for anyone in the street life
