Bank Notes
Ken Habarta has just written a book about the notes that people use to rob banks. He has been posting daily examples of the notes on the blog Bank Notes. Each note is accompanied by a picture of the robber and an icon indicating if the robbery was successful or not. The website is searchable, in case you are only interested in robberies involving polite notes (search for the word “thanks” and “please”).
The thing that makes this interesting for me is the icon which shows the success or failure of the heist. It seems like the most straightforward notes (with death threat) have a better rate of success. Then again, who knows what the actual circumstances were? (Not me)
