I understand that they wouldn’t get involved in regular local mail mailbox crime, but this was inside of a US Post Office.
That has to be the easiest layup possible a USPIS agent to get a case closure off from, but now I’m really curious about what jurisdiction local police or sheriff’s deputies even have when dealing with crimes that occur inside of the post office, which I’m fairly certain are federal buildings.
I always thought that crimes that occur on federal property, or land, are automatically assigned to federal law enforcement.
