I didn't say "don't fix anything because so much is broken" so it seems like you do subscribe to it since you brought it up.
I'm just trying to keep up with you moving the goalposts. First it was "grand juries aren't remotely the problematic part" to "they're not the biggest problem".
You asked why I commented originally, I explained, then refuted you with a source. Don't get mad at me for your own spurious claim.
