Firstly, I don't think the difference between civil and criminal law is particularly significant to the surrounding discourse when many people are seemingly confused about who was on trial in the first place.
I'd argue the general public's ignorance towards the difference between civil and criminal court, and civil and criminal procedure, was precisely the phenomenon exploited by media to muddy the waters for profit -- to the point, as you said, people were unable to recognize who was plaintiff and who was defendant.
Secondly, defamation is weird. While technically decided by the preponderance of evidence, responsibility typically rests with the person accused of defamation to demonstrate that their statements were not defamatory, usually by presenting evidence that the statements were either true or were reasonable based on commonly held beliefs at the time.
That doesn't change the burden of proof or the evidentiary standard, that's just how the nature of how counter-claims must be in defamation cases. At the end of the day, juries are still deciding whose claims are more likely to be true based upon evidence presented.
By the way, interesting side note to this: truth actually isn't an
absolute defense against defamation in the way people conceive it. That is to say, demonstrating truth means victory for defendants by default, regardless of other circumstances. There actually have been defamation suits in which defendant's claims were true, but because of other intervening variables (aggravating factors, proof of malice beyond doubt, untimely verification of facts), juries ruled in favor of plaintiffs
anyways.
Back when I had Lexis and Westlaw access, I snooped around to find examples of this due to an argument I was in at the time. Among other cases, I actually found one (from Washington state if I remember right) where the claim of dispute was
only discovered to be true by accident during discovery. Up until that point, the defendants -- a newspaper outlet and its editor-in-chief -- had been operating under full belief the claims were
false...to the point plaintiffs were able to provide evidence the EiC insisted the story be run with the specific intent of defaming the plaintiff. They had a tape recording of a staff meeting, if I remember right.
Trial judge wasn't having it, denied defense's motion for dismissal, and the plaintiff went on to win the case. The evidence against the outlet and its EiC was
so damning, the truth-value of the original claim was deemed irrelevant.
We should not be using 19th century trials as the basis for what constitutes a reasonable level of scrutiny or public involvement. Only a hundred years before Dreyfus was tried in France, Robert-Francois Damiens was tortured and horrifically torn to pieces in a public square, yet that doesn't make a bit of difference to what we should tolerate now. Spectacular justice belongs in history.
Actually, my point is media coverage of court cases under (especially late-stage) capitalism is unreasoned by default, and this has pretty much always been the case across the entire legal spectrum whether we care to admit it or not. What was true for Alfred Dreyfus, and Sacco and Vanzetti, was equally true for Adolf Eichmann, O.J. Simpson, Casey Anthony, and Kyle Rittenhouse: truth rarely withstands the rigor of profit-hungry media.
We know the answer to that, too: nobody's (well, except the press, I suppose). A bunch of reporters shouldn't be able to guide the outcome of a trial in any direction. It's impossible to completely negate their influence, of course, but it's far from impossible to limit it.
That's what I'm getting at. The louder and more obnoxious the noise machine gets, the less credibility it
ought to have. We just exist at this time at an unholy nexus between popular media illiteracy, late-stage capitalism, and dystopian secularized prosperity doctrine, where we treat the biggest assholes in the room as the most credible for no other reason than they have the biggest megaphones and make the most money. That's as true for the likes of Nancy Grace and Piers Morgan, as it is third-rate Gawker content millers and YouTube outrage grifters within their individual blast radii.
It would not be possible for a juror to miss the overwhelming deluge of "Look how fucking crazy she is in this video!?" and "Depp lawyer DESTROYS Heard lawyer OMFG!!" clips posted in their millions throughout the trial. I was pretty much unable to go online without being inundated by that stuff.
Exposure is not synonymous to influence, however. Just because someone
sees a given unit of content, does not mean they
consume that unit, and even
consuming that unit does not mean the consumer finds it
persuasive.
