For once yes. Grand Juries at the time of the Constitution were a safeguard against arbitrary and unjust prosecutions. The rulers have since changed what a grand jury is to make it the opposite, a tool of the prosecutors.

Luckily the prosecutors for this administration are so arrogant and incompetent they haven't been able to maintain that facade of trustworthiness which the masses still afford to dickheads in suits with position.

Of course the judges are so bad it often doesn't matter, especially when it's in a shitholy jurisdiction, like those protesters at the Texas Ice that got kangarooed by their dipshit hanging judge down there under preposterous, blatantly unconstitutional charges, cancelling the 1st amendment.

Curiously, when I was drafted into jury duty here in California, we were shown a video that said something like The people are society's last line of defense against bad law.

I took it personally, figuring it was my duty to not enforce any law that was unjust or protect any institution that was cruel. But I didn't get selected.
