I said this in another thread, but FBI, CIA, and DHS would probably get folded into DOD and delegated to the National Guard (CIA would be active duty, probably Army or Space Force). Repeal Posse Comitatus and the guard could easily do the FBI and Homeland stuff, but here's the kicker: They would be assigned to the States and not the Federal govt. That would all but eliminate the corruption because the management would be decentralized. Each Governor or AG would command those organizations. DOD could make the regulations (like the Army National Guard follows Army regs) and could have a top-level command like NGB.

IRS too please
