So better that more innocents be punished than risk any guilty going free? Truly, your love of the strictest "definition" of democracy is baffling, though I think most would vote against you.
No, Democracy gets it wrong in both directions with more of the guilty set free and more of the innocent sent to prison at least compared to a hypothetical ideal system.
Mob justice can be true justice. As in this case precisely, there was proof that a court refused to listen to.
At some point you need to worry about deep fakes, etc, but there's still cases where the accused more or less says they are guilty and flips the court off and everybody acts like nothing can be done about it.
