So far, all I’ve found is a 2018 publication by the Police Executive Research Forum, entitled “The Changing Nature of Crime And Criminal Investigations”. It’s a 67 page document, and I’m curious to see if it discusses how their investigation tactics may have changed, and if so, whether the aforementioned tactic is mentioned as being included.
There is some merit to the classification, considering people in “2nd/3rd world countries” walk into grocery stores in the US and are so overwhelmed by all the abundant meat and produce and clothes that are freely accessible, that they have to go back outside to collect themselves. It’s not your ethnicity that determines if a country is a 1st/2nd/3rd world country. it’s how far their infrastructure has advanced, and their quality of living. Don’t like it, become a politician or businessman, do your darndest to be successful, and then make it your purpose in life to use your wealth/influence to advance infrastructural development in countries that don’t have the same quality of life as countries like Japan or the US.
