'Why wouldn't they just leave?'
Well, why won't we?
shareThis was one of the things the book explains. The residents have an unspoken groupthink that includes:
* not leaving the building
* discouraging police intervention (in the book, it is a group of residents leaving for work that tell the police officer that everything is alright)
* not using firearms
Uncomfortably comfortable.
Ever tried, ever failed?
No matter.
Try again, fail again.
Fail better.
Kind of like Exterminating Angel.
Thumbs Up, Thumbs Down and a Wagging Finger of Shame
