If they investigate and take into custody suspected criminals for prosecution, how is that not policing?

federal crimes are enabled by specific authority
contained in the constitution (Interstate Commerce Clause, for the most part)
or in laws enabled by treaty

"taking into custody" is policing

and the feds do so in cases where they have jurisdiction

murder is a state crime, and does not grant federal jurisdiction

So ultimately there is federal authority to police, but it is limmitted

yes, of course

hence federal prisons holding millions of inmates

or hundreds of thousands, or whatever it is

Feds often work closesly with states either way anyway from what I understand

indeed

The federal government has the right to police their own laws. Remember the FBI was borne of the effort to enforce Prohibition.

Simmilar to how they might even work outside of the country

yes

although the feds have greater jurisdiction within the several states
than they do in foreign countries

yes

Prohibition was specifically a Federal Law - an amendment. A disaster of an amendment since it was the only one that specifically took away liberty rather then preserve it.

Hence why it needed to be policed

On the topic above, does anyone know why circumcission is even a standard still in the U.S.?

Gynocentrism.

@DrYuriMom https://en.wikipedia.org/wiki/Federal_Alcohol_Administration

People blame FDR for the rise in federal power but honestly I place that blame firmly on the massive apparatus it took to try to enforce prohibition.

^ dig into that one 😃

We just talked about this. The right of parents to mutilate their children is decided on a state by state basis.

Just like murder and rape.

provided no interstate commerce, yes @Bookworm
( and no federal legislation enacted pursuant to an enabling treaty to end genital mutilation )

hmm

Do parents always explicity choose or is it the standard to circumcise

Parents decide.

Why do parents choose to?

My understanding is that the parents decide. I'm not aware of any medical practice that circumcises by default.

Religious reasons would probably be the most likely one.

I thought Americans were mostly Christian though

Possible health concerns. I believe my cousin had some severe genital infection related to his foreskin.

There is a common myth in the US that it is healthier and cleaner to do so

Yes, and Christianity is an Abrahamic religion and maintained some cultural traditions, in some cases including circumcision.

You guys should ask me

I am aware of that, that is why I was wondering if it was a standard
(In reagard to supposedly health concerns)

I am the ideal example!

@Bookworm New testament is explicitly against circumcission

Or, at the very least, Paul.
