If you ask me, in order to fully convince the court not to press legal charges against Spider-Man in the "murder" of Mysterio, Murdock could've conducted a thorough investigation into the circumstances of the Battle of London to verify the authenticity of Mysterio's framing of Peter, present the evidence to the jury, and then have them publicized. I can't help but think that Matt's involvement, albeit brief, in Spider-Man: No Way Home was missing something like that. I mean, when something as controversial as framing someone for murder and orchestrating an attack, like Mysterio did, is carried out in the M.C.U., a much stronger sense of closure like what I'm suggesting should be carried out, even if sentiment against Spider-Man still becomes increasingly more negative, since a lot of people out there in this day and age believe the lies. As unfortunately unlikely as this sounds, it could've helped bring the public pressure unfairly mounted against Spidey to a much stronger sense of finality, even if the public still somewhat sided with Mysterio's perspective, as the truth would've become public knowledge.
