Do you see the connection between legal-sized paper, the use of Latin in both the legal and medical professions and the fact that doctor handwriting is nearly impossible for a layperson to decipher?
The hidden agenda was to keep legal and medical knowledge from the commoners. To this day, it's still a PIA to photocopy and file 8" x 14" paper and understand a doctor's written prescription or "marginalia" (handwritten notes along the margins of typed documents.
The most valuable knowledge dropped on this legalfag was the concept of "legal critical thinking". The basic premise of CLT is that there are approximately two dozen template arguments which an attorney/judge can deftly flip pro to con and vice versa in "manufacturing" or "backing into" any given legal conclusion or judgement. We were trained to "speed flip" hypothetical legal opinions using any combination of 4 - 6 of these template circular arguments and, importantly, to quickly spot them in all legal cases studied in the different areas of law.
We were drilled to first find and understand the biography or socio-economic family background of each of the SC Justices (AND which President nominated them to the bench) current and former before preceding to analyze his or her written opinions. We were similarly drilled to do the same with all judges we would face in the future once passing and being admitted to the bar.
Eyeopening.
