I don't like the central thought:

Neither idea is a good one. American democracy has survived nearly four years of Trump; it can survive nine days more.

If the mob had succeeded in hanging Mike Pence or killing Pelosi, would that thought still hold? Is desecrating the capitol and losing 5 lives, let alone losing an extra 200,000 lives to Covid surviving 4 years?

He seems incapable of dispatching his duty. As the capitol was ransacked, he watched on TV and didn't respond to all the pleas to authorize the National Guard to come in.

Congress is not able to hold a person guilty of a crime.

I may be wrong but if the country wants to place Trump on trial for having committed a felony, I think that he can be arrested on the afternoon immediately after Biden's inauguration and held for trial.

Except for impeachment, right?

No.

Impeachment does not constitute finding a person guilty of a crime.

Impeachment can remove someone from office and can also disqualify him from future office but it does not constitute convicting the person of a crime.

Nailed it, @Chris! 👍
