It’s easy to talk out of your ass about how you would have done a better job, but you clearly have no idea what the circumstances were that the prosecution team was dealing with. This particular piece of evidence for example was attempted to be admitted but was denied by the judge for being “irrelevant to the case.” The prosecution was fighting a court stacked against them and you would have had a hard time as well.
Or you could do that by default while very selectively supporting specific artists. That way you can both stay within your means and exercise moral discretion over who you support.
