The fundamental flaw of the constitution is that it had no ethics built in, it’s up to the voters to pick better, our press to report truthfully without bias and those have failed as well.
Yes, that would have been a really good intent to make explicit, to guide the courts.
I think of that when the Supreme Court or a state court rules process is more important than a convicts demonstrable (with new evidence that has come to light) innocence. Really horrific given that one out of eight death row inmates are exonerated. That level of bad convictions being overturned despite all the difficulties doing that, strongly suggests that a great many innocent people are still executed.
Another thing I wish the constitution did: Explicitly and universally enshrine decentralization. Not just the implicit decentralization of checks and balances only within the government.
I.e. party seat limits, independent federal and state parties, etc. For any kind of political group or coordination.
Where enough decentralization is enforced, a stable majority interest is maintained (even as who is the majority may change) for no minority to be able to break those requirements.
But where centralization is allowed, it is an eternal fight to hold it back.
