Answer

Wow you are reading some difficult stuff!  I think the author is using a lot symbolic language and to get all of the meaning you will need more context.  Basically your answer 1 is closest.  There are several types of people in the 'immobile mob' -- all are unwitting bystanders who haven't 'read the script'.  The meaning of 'read the script' -- whether symbolic or literal is something you will have to figure out from the rest of the context.  The author gives examples of the unwitting bystanders -- some might be tourists and others are certainly 'pigeons'.   The author is alomst certainly speaking symbolically here -- not literal birds but 'pigeons' is slang for people who are easy targets either to be fooled or to have things stolen from them.  All are literally 'frozen out'.
