If you have enough data, i wonder how much of this digging can be automated these days with good LLM prompts. Doing it manually is very time-consuming.
The real work doesn't happen in the LLM.
Having worked with LLMs over the past year+ trying to get them to do useful things in various contexts, the real work is typically pretty boring data acquisition (e.g. scraping) + ETL and then making that data available to the LLM.
I think this whenever I read a modern detective novel (Bosch). So much of their work seems to be looking up data from different databases and trying to make connections or recognize patterns.
I assume the FBI or whomever has automated this to some degree already, and I really hope someone does a great writeup of how LLMs/agents can do even more.
