I believe Federal police are the FBI. As I said it was a generic government list and they were probably talking about state governments as well.
I should have looked farther before posting.
But I still maintain that with federalized crimes there should be federal prisons.
Defund both of em as far as I am concerned the FBI have no business existing.
Domestic matters should be the Provence of the States.
therefore the Federal goverment should have very limited uses for non-military prisons.
