There are three classes of countries, as I see it, that indict or jail leaders out-of-power in the opposition. (1) dictatorships like Myanmar (2) quasi-dictatorships acting under a veil of democracy, like Brazil (3) places on the brink of civil rupture, like Israel.
To say that this was intended by the Constitution of a breakaway American Republic is mad, because no sane English colonist would have chosen to renounce the crown if they'd known an idiot like Donald J Trump would be President 200 years later. Of course power should be held to account! As many people here have said, Presidents that committed war crimes would be a better target for prosecution. Or Trump's own crimes in office would be.
This prosecution under these auspices and for these reasons places us (Americans) squarely in the realm of third world semi-democracies.
I don't know if anyone has brought this up, but I hope Joe Biden will be wise enough to immediately issue Trump a pardon and bring this to a close. If Trump is indicted again for something serious, like insurrection, that would be a different matter. It's not possible to divide politics from law in a case where the defendant has a rabid political following and was the President of the country (as insane as that seems). Biden needs to pardon him right away.
