Theory. Prosecution might actually be trying to protect rittenhouse from the jury. Defense and prosecutors often work together to find common interest. Defense wants Kyle off. Prosecution wants to claim he tried (if anything too hard). And the left is too stupid to see the prosecution sabatoging his own case because they are moronic and only see "struggle against an unfair system", and their minds are glued to any narrative that rhymes with a past narrative and can never do any real analysis so they will never catch on.
