Not sure why we have both the FBI and the U.S. Marshall’s Service - seems redundant, but since around 1900, 80% of the feds have become redundant, wasteful, and 80% unconstitutional. The constitutionally supportable department of the DOJ is a mess.
Of course the 80% of the alphabet soup of federal departments, agencies, and bureaucracies which are wholly unconstitutional should be nuked. That would help.
Hopefully, during the next 7 years, that will be corrected - would give us more than enough money for infrastructure/ wall a,d more tax cuts ... well, we wouldn’t NEED to tax cuts if we eliminate the IRS
