Can't disagree with your reasoning, but why the duplication of work between departments? Are they really just separate fiefdoms, who refuse to share intel with each other?
Probably so. Thank Jamie Gorelick.
The short answer to your question is - yes. And it’s worse than you can imagine.
You’d be dismayed to see how local and state law enforcement and even federal agencies DON’T share information. CIA doesn’t talk to FBI (Gorelick’s wall). FBI doesn’t talk to state and local. State and local align with each other and DIA to go around the FBI. NYPD even sends people overseas to go around CIA and the FBI. Law enforcement doesn’t talk to the other emergency services.
Ten years on and BILLIONS spent to enhance intel sharing, and we’ve only moved inches down a road that is miles long.
