Yes, the US Marshall Service is part of the Department of Justice.

And, although they operate under the direction of the Attorney General, the following brings up an interesting point:
The Marshals Service serves as the enforcement and security arm of the U.S. federal judiciary
If the court issues an order and the attorney general subsequently refuses to enforce that order, couldn’t the court then issue an order placing the attorney general under arrest?
They won’t but even if they hypothetically tried to, I doubt they could. We’re talking about Marshalls who have spent their career in the DoJ working alongside and for the Executive Branch. The courts try to tell the AG to order the Marshalls to do something and the AG refuses. So the courts try to deputize the Marshalls and give direct orders and we’re to expect the Marshalls will go against the people they’ve been loyal to their entire careers?
Oh, I wasn’t thinking they’d deputize a Marshall. Not that it makes any difference, though. Anybody with training sufficient for the job is probably a fucking pig Nazi anyway
There are plenty of ex military with the training and ethics to choose from. But with the 6-4 SCROTUS? Fat chance.
They’re cops. They don’t get training. Just a gun.
