I'm prone to guess the following:
One or two of the jury will hold out for guilty just because they're lefty squirrels or scared of BLM&co and they'll come back reporting themselves Hung.
The Judge will then give 'em that "mistrial with prejudice".
The Judge, Rittenhouse and most of the jury will then all be candidates for Witness Protection Program (if there is any part of the government left that can be trusted) or just pack up and go someplace out of the line of fire and in a Constitutional Carry state.
I’m pretty certain that Kyle would be welcomed in either Florida or Texas . . .
