searched "PROTECTIVE ORDER GOVERNING UNCLASSIFIED DISCOVERY" clicked one of the random links not knowing wtf any of it is, could be way off base, not lawfag anon:
"This pocket guide is about the use of protective orders to keep discovery confidential in both civil and criminal cases. Although a
strong presumption of public access applies to evidence admitted
at trial or considered by the court to decide the merits of a case,
parties now undertake discovery away from the court. Experience
has proved confidentiality protective orders to grease the wheels of
discovery in many cases. Parties are often more willing to produce
requested discovery when they know that such production does not
necessarily make the information public."
appears to be something along the lines of protecting source of info submitted for trials
