It seems to me that teaching potential demagogues that they will go unpunished if it's sufficiently inconvenient is a bad lesson to teach if you want to keep a republic.

You can't impeach or have any justice done in two weeks. It's just not worth it.

If there's some kind of crime that's been committed and it can be prosecuted successfully, then by all means after he's out of office. I don't think that's the case though.

You can prevent him from pardoning the rioters. You can bar him from running again.

Impeachment actually does things other express disappointment.

I have been hearing this same shit for 4 years and look at this smoking crater.

If you take harsh action now, you make it clear to any future copy-cats that this behaviour will not be tolerated.

There's a reason why kings typically had the parts of traitors nailed to the city gate, after all.
