It’s not a practice round for a trial. It is the first safety check of “Is there even plausibly enough evidence to go to trial?” or more specifically “If everything the prosecutin is claiming is true, is that enough for a trial?” which is why it nearly always is.

I highly disagree with your assessment, and it sounds like you don’t really understand the courts. Now, you may be simplifying, and if so, then my ‘accusation’ is off-base, so don’t take it too seriously.

I’m no legal expert, but I’ve followed enough to see how 99% of legal representations on television (i.e. court dramas) are laughably inaccurate.

So I go back to my point - like when see a real judge on a youtube video of a courtroom proceeding and they do a probable cause hearing - basically similar principles to a grand jury - it matters why they throw something out. It matters a lot. Is it a technicality that they can overcome and resubmit the case, or is it a fundamental flaw?
