Trump Steps In

It appears that President Trump is tired of the lawlessness in the several US cities and is dispatching federal law enforcement to take action.

I can hear the media now.  "What authority do federal officers have to enforce the law?"

That's easy.  The basic law enforcement officer in any district is the US Marshall, who is authorized, among other things to: 28 U.S. Code § 566

(d) Each United States marshal, deputy marshal, and any other official of the Service as may be designated by the Director may carry firearms and make arrests without warrant for any offense against the United States committed in his or her presence, or for any felony cognizable under the laws of the United States if he or she has reasonable grounds to believe that the person to be arrested has committed or is committing such felony.

That looks, to me, to be a pretty broad commission to enforce the law anywhere in the United States.  US Marshals have had that authority since the beginning, and used it frequently in the early years, when law and order was a scarce commodity.  Al a sitting US Marshall needs to do, is to deputize anyone who is working in his jurisdiction.  Problem solved.

Any media weenie who asks about authority should do his homeworrk.
