This was joking about GP, if that was not clear. A society simply cannot function with the cartoon levels of crime seen in Batman or Grand Theft Auto; People leave for abroad. Planning what you should do after you're kidnapped is a function reserved for if your life is too much of an apocalyptic disaster to plan not to be kidnapped, and even South Africa and El Salvador at their worst levels of unrest were not really at that level.
I don't think you really know what you're talking about and I'm struggling to answer to your dumb "joke". I was sharing a rough anecdote as an example of how technology fails when designed in isolation and your answer was ... Lol, Batman.
I invite you to read about daily life in latinamerica. Kidnappings were very common in the early 2000s and millions of people indeed leave leading to some of the biggest human refugee crises in the world ... Lol, GTA
Crazy.
What city was this, if you don't mind me asking?
