Just the Facts, Ma'am

We recently had an invigorating discussion about facts, so I thought I'd actually look the word up. I know, linguists tell us that dictionaries don't define words, they document usage. I'll make no appeals to authority here! Nonetheless, it's an interesting selection from the OED. Who knew that facts can be acts, disputed, and guilt? Or that Sgt. Friday never said,"Just the facts, Ma'am"?

fact, n., int., and adv.

Etymology:  < classical Latin factum deed, action, event, occurrence, achievement, misdeed, real happening, result of doing, something done, in post-classical Latin also thing that has really occurred or is actually the case, thing known to be true (11th cent.; from 13th cent. in British sources), case, legal dispute (from 13th cent. in British sources), use as noun of neuter past participle of facere to make, do < an extended form of the Indo-European base of do v.

 I. Senses relating primarily to action.

1. An action, a deed, a course of conduct; (formerly also occas.) †an effect, a result. Also as a mass noun: action, deeds, as opposed to words. Now somewhat rare.

Interesting that the word also carries the meaning of actions, deeds, events. Real things, indeed.

II. Senses relating primarily to truth.

6. Law
 a. The sum of circumstances and incidents of a case, looked at apart from their legal bearing.
 b. In pl. with the same sense. Also: items of information used or usable as evidence.

7. That which is known (or firmly believed) to be real or true; what has actually happened or is the case; truth attested by direct observation or authentic testimony; reality.

Firmly believed?

8a. A thing that has really occurred or is actually the case; a thing certainly known to be a real occurrence or to represent the truth. Hence: a particular truth known by actual observation or authentic testimony, as opposed to an inference, a conjecture, or a fiction; a datum of experience, as distinguished from the conclusions that may be based on it.

b. With the and following clause or preposition.
 (a) The actual occurrence of an event; the real existence of a situation or state of affairs.
E.g.: 1986   Amer. Scholar 65 572/1   The fact of their nationality colors the way men and women think, particularly about politics and society.
(b) The circumstance that something is the case.

 c. Uses emphasizing the truth of an assertion, esp. in fixed phrases.
 (a) The (honest) truth. Freq. in the fact is with that-clause, esp. asserting something surprising, unwelcome, or controversial, or making an admission; also colloq. (orig. U.S.) without the.
 (b) A true statement. Freq. in (and) that's a fact.

d. A person, an institution, etc., undoubtedly in existence; a person or thing experienced or seen.

9 is interesting because it goes against what I think a fact is. I'll leave all the example sentences.

9. A piece of information allegedly or conceivably true; something presented as a fact (in sense A. 8a) but which is disputed or unproven; (more strongly) an unproved assertion, an allegation.
