It has never been established that any insurrection took place on January 6, 2021. A mob was gathered, but except for one unarmed person being killed, and a number of windows broken, it was probably one of the most “peaceful” demonstrations in any major US city in the previous three years.
Unlawful, was it? By what measure? What does “lawful” even MEAN in this context?
True assessment - the protest has not been adjudicated to have risen to the level of an insurrection (especially compared to the ‘mostly peaceful” BLM summer of destruction).
Additionally, depriving someone otherwise qualified of the right to run for President requires due process. DJT has not been charged with insurrection, much less found guilty of same.
