The article discusses the 25-year legacy of mass surveillance in the US, which began as a response to the 9/11 attacks and has since expanded to become a routine tool used by law enforcement and private companies. The authors argue that this shift has had profound implications for Americans' rights and freedoms, particularly with regards to the Fourth Amendment.

This has led to a pipeline of information from private collection to governmental collection, with increasing use of AI technologies and potential for abuse.
