What is the difference between John Durham, US Attorney for Connecticut, and John Durham, Special Counsel?

Been poking around the interwebz, and a light bulb went off.

Why did Q post "Durham" as his last post (so far)?

Why did Barr announce that Durham has been appointed Special Counsel?

Why did Barr make that move before the election, but announce it after?

Did we miss an important clue?

What is the difference between John Durham, US Attorney for Connecticut, and John Durham, Special Counsel?

This is … BIG! YUUUGE, even.

When a US Attorney for Connecticut wants to take a criminal case to court, but the case must be filed in some federal court other than in Connecticut (because the crime occurred elsewhere, for example), he MUST REFER the case to a DIFFERENT US attorney and have THEM do the prosecution. As US Attorney for Connecticut, Durham would have no legal authority to prosecute in California or Michigan or Georgia. He would only have authority in Connecticut.

But as a Special Counsel, John Durham has WHATEVER LEGAL AUTHORITY THAT AG BILL BARR GAVE HIM, and that could include prosecuting ANYONE in ANY federal court.

Q and Barr are both telling us that Durham is about to make his move.
