The MSM:
* Spared no lie in trying to poison the jury pool against Rittenhouse, and failed (the outcome being irrelevant to any lawsuits Rittenhouse might file);
* Printed and broadcast lurid tendentious lies long after the lies were known to be false; this will be the core of any lawsuits Rittenhouse might file.
My WAG is that MSM people and companies he sues will be forced to use the "Public Figure" defense, which makes it nearly impossible for a celeb or national-level pol to win a slander or libel lawsuit. That defense is the basis for the NY judge ruling against Sarah Palin (blatantly wrongly, IMO). MSM companies tried that with Nick Sandmann, and were pretty much forced to settle, because they had made him a "Public Figure". That is the problem on which national-level MSM types may founder. Rittenhouse's case should never have grown larger than Wisconsin or the Wisconsin-Illinois area. The MSM chose to make it a national-level story.
If the MSM people and companies he sues try the "Public Figure" defense, all of DU (plus or minus brooklynite[ and/or former9thward) will lap it up and think Rittenhouse's cases doomed. What those DUpipo will refuse to recognize is that a "Public Figure" defense, when used alone, would mean that the MSM person/company has conceded that what they published or broadcast was false, and they should have known it or did but got careless.
