To be fair, the justice system was never designed to or for protection of the Republic. It should work slow as state removal of liberty is big AF.
The people through their congressional representatives were given the ability to impeach, remove, and restrict from office those who would imperil our system of government. There's no such thing as 'beyond a reasonable doubt' in politics.
However, half the people are broken in their brains. Partisan interests have trumped loyalty to the constitution due to monied gentry, religious zealots, and legally anthropomorphic corporations using their $ and power to pervert the very system of government meant to represent the people. Instead it represents entrenched wealth and ideologues who themselves prop up power hungry sociopaths who use politics as a personal means to enrich themselves.
And therefore the only real lever designed to protect us has been perverted to the point where we have to rely of the justice system as a last resort.
