Agricola:
Again, you miss the point while making it for me.
Your historical namesake (whom you presumably admire) was an invader laboring for an alien power whose interest in the inhabitants was solely to enrich themselves through taxation via pacification and domestication. Ie:robbery (writ large.) The native inhabits response to this robbery attempt would be of questionable legal virtue under current British law.
Your disagreement with the brief biography of "Agricola" from dictionary.com is not one of fact, but language. The intent was that under Agricola's term, the process of taking control of Britannia was completed, not necessarily that he himself had begun and ended the process. You yourself wrote, "Once Agricola had conquered the remainder of the country following the battle of Mons Graupius..." which would seem to bear out my claim.
As to imaginary lines, and on which side worthiness lies, I am sure that one could have an interesting conversation were one to ask a Scot, a Welshman, an Irishman, and a few others.
As to the jury process, the Simpson trial provided a graphic demonstration between FACT and TRUTH. (TRUTH being subjective, FACT being objective.) TRUTH won out over FACT, in that instance (in fairness, most legal systems do not seem to make a distinction between the two.) Other occassions:
-The British Parliment held TRUE the idea that their colonies on the Atlantic seaboard in the Americas would be taxed to pay part of the cost of the (then) latest of the wars between England and France. In FACT, this was demonstrated to not be correct.
-It was held TRUE that "Britannia Ruled the Waves", and was also FACT for a good number of years. By the early 20th Century, this FACT was conclusively demonstrated to be incorrect, but was nontheless held to be TRUE for a couple more decades.
While Simpsons not guilty plea was found to be TRUE, only a deranged lemming/LA County Jury could find that to be FACT. This was later demonstrated when Simpson was found guilty under civil, not criminal law.
