Took a peak at live feed and it seems you may be right. Rittenhouse was giving details about what he was doing there and about people he was helping with first aid, an of being pepper sprayed without retaliating. Stuff I kind of doubt the prosecution wants the jury to know about.
Yes, and stuff that may be hard for the Defense team to bring into the trial any other way. May be ruled irrelevant, or maybe hard to corroborate or get witnesses to show up or testify.
Also just read he (basically) claimed he didn’t bring the rifle with him from IL but that it was in WI the entire time which was part of the media chatter (”he took a gun across state lines”) but not sure how that aspect played in the trial.
