The Broward County School Board used an idiot’s form of “redaction” on a PDF before sending it to the media. The Sun Sentinel removed the blackout layer from the file and found newsworthy information on shooter Nikolas Cruz. They published it. Judge Elizabeth Scherer flew into a rage. She decreed, “From now on if I have to specifically write word for word exactly what you are and are not permitted to print… then I’ll do that.”
That’s called prior restraint, or censorship.
