it was helpful start. There does not seem to be a way to get justice to the criminals within the system. What you are presenting gets at that in a way.
As per a quorum... my opinion is we need a at least a certain percent weighing in. This is the quorum (75% like you mentioned might be right)and then of those weighing in/demanding we can't rely on a simple majority. The bar needs to be higher than that. 2/3 perhaps. It would be a significant improvement but maybe I am not being harsh enough since that is only around 50% of all adults.
People seem more concerned about who they are electing versus what is being done.
