I don't see how them losing when literally every shred of evidence is against them is proof that they don't rig the system.

Ah well, just like with Kim Potter, you make insane predictions and then learn nothing when predictably, they do not pan out.

Sometimes you can't rig it hard enough to counterweight the evidence against you.

Why were charges not quietly dropped, as you were so sure would happen with Kim Potter?

You could even say that they allowed this to happen because it gives the system an illusion of fairness if they lose trials where they have literally no argument.

Oh, this is a good one.
