He won’t have to rule on it when the verdict is not guilty.
Defense made the motion to preserve the issue on appeal if Rittenhouse is somehow found guilty on any charge.
And, if Rittenhouse is found guilty on the most minor charge, the judge could grant this motion for mistrial on that charge. The prosecution isn’t going to retry that case.
Well, I ain't a lawyer nor do I play one on TV, so I'll defer to your judgement here, buckle in and hold on for the verdict! Anyone with 2 brain cells to rub together can see the clear cut case of self defense, period. I just hope the jurors have 2 brain cells to rub together.
