Arguments today on Presidential immunity (updated)

Oral Arguments were about as expected. Both sides being questioned on the obvious issues involved. What actions would be protected under official and what safeguards are in place to make sure rogue prosecutors are not allowed to charge Presidents for official decisions made (thus you criminalize politics).

Most everyone expects the court to rule against the argument of Presidential immunity, even as such a thing has been the unwritten rule (not charging Presidents with crimes for actions as President).

So where is the stretch between the unwritten rule (or the previously unwritten rule) and making it an actual legal precedent? If the concept of treating the President differently (requiring impeachment and Senate trial) has been the standard for over two centuries? Why would Joe Biden and Jack Smith be allowed to change this now?

One thing that came up was the idea of impeachment and how this plays into the situation. The argument being that only a impeachment conviction should trigger criminal prosecution for actions that took place during Presidency. Well how about an impeachment where the Senate acquitted the President during that trial? Would it be appropriate (as is happening now) for the Senate to find the President not guilty and then have that President get out of office and be charged with that crime? Because that is exactly what is happening with the Jack Smith Jan 6th charge. The House impeached Trump for his actions on Jan 6th, but the Senate did not convict him. Why should Democrats then be allowed to push for a special counsel to bring charges when the impeachment fails?

Update: Many people believe that the conservative members of the court are looking at finding some limited official duty type situations where Presidents should be immune from prosecution. The suggestion here is that this would be bad news for Jack Smith and the Biden administration, as the cases may need to be evaluated over again to make sure that nothing in the indictments or charges would be protected. If so, the cases would be almost guaranteed to move well beyond the election. Jack Smith has a hard enough chore in front of him to get either of these cases up before the election, regardless. But even a partial victory for Trump would toss a big wrench into anything happening before November.
