@Dedonus So you think the defense would want/require any of the heroes involved to take the stand? You mentioned how he kidnapped some of those currently involved in the arc and that could be an interesting talking point, might even create some dissolution between the public and the metahumans.
The accused has the right to face those who accused them. The problem is that some of the heroes would not want to be cross examined by the defense. They would have to be present in their civilian identities and the defense could easily out them for being metahumans. And even if onky Kelly testifies because her metahuman status is public knowledge (because of a youtube video from earlier in this game), the defense could still ask her. And if they plead the 5th, then I think the jury has to ignore their entire testimony. I could be wrong on that last part, so don't take my word for it.
