I believe that the FBI should have no arrests powers in the States constitutionally.
There is no provision for a Federal police agency in the Constitution.
The FBI should be required to get a warrant for arrest in a state court and then get a state LEO to serve the warrant.
True. The Constitution defines only 3 federal crimes: treason, piracy and counterfeiting. But it authorizes Congress to create new federal offenses. Since the Founding, Congress has created over 10,000 federal offenses, and that is why we have the FBI.
To get rid of the FBI, you need to pare down the number of federal offenses and restore police powers to the states.
“There is no provision for a Federal police agency in the Constitution.”
You are 100% correct.
Normal police and criminal powers reside with the states.
Armed Federal officers are nothing more than a standing mercenary army stationed among us...120,000 of them at last count.
Other than US Marshals, Postal Police, and maybe Customs arming these thugs and thuglets is a very recent development.
The Secret Service is not Constitutionally specified/permitted other than as customs/currency agents for Treasury/tariffs.....Lincoln used Pinkerton’s.
Their body guard duties I guess would be extensions of the DC Federal/Capitol police authority over Federal lands and security.
Yet more checks/balances torched for convenience and now accepted as normal.
