The FBI went downhill when the Director at the time decided that every investigation be run out of HQ. This was either Freeh or Mueller working with the top assistants. Then it got worse when they decided to focus on intelligence gathering on all Americans that are a threat to the deep state.

With today's Zoom culture, never mind its successors, there is no such thing as "scattering."
