Nothing about it requires a dictator. You vote for politicians who repeal laws that don't have widespread consensus, when enough people vote for them they get repealed. Ideally you then do something that makes it more difficult to re-pass them.

The procedures aren't loopholes. They're prerequisites for a conviction. They by no means make a conviction impossible, but you have to do the work.
> At the same time, you have #MeToo, Harvey Weinstein, etc, which has resulted in the expansion of sexual crimes and punishments, and elimination of statutes of limitations, partly because procedural protections have made it extremely difficult to prosecute past behaviors, not because they strictly weren't already cognizable crimes.
The problem here is not procedural rules at all. It's evidentiary difficulties. How do you distinguish between someone who consents but then has regrets and changes their story, or someone who has sex with someone wealthy in order to extort them for money, and someone who was actually sexually assaulted?
There is no perfect solution to that, but "innocent until proven guilty" is the only sane one. What you then need is a system that can uphold that standard even when there is pressure not to.
> That suggests that by giving back more discretion to the system, not less, it's possible and, IMO, much more likely we could end up with a more fair system all around.
It suggests that when you give more discretion to the system and the system favors you at this moment in time, you get what you want, for now.
But then there is another election and you may not like what someone else does with that discretion.
