The only way to know the answer to this question would be to actually try the case in front of a Michigan Jury. One thing for certain however is that Kyle Rittenhouse would have been allowed to raise a claim of self defense had the case happened here in Michigan. Presumably, if it was the exact same testimony and evidence, same jurors, judge and prosecutor, then yes, Kyle Rittenhouse would have been acquitted here in Michigan too.
This is all speculation, but a brand-new case in Michigan may shed light on the question. The name of the case is People of the State of Michigan v Leandrew Martin. The case arose out of the Jackson County Circuit Court, and was decided on November 18, 2021. In this case, the Michigan Court of Appeals set aside multiple felony convictions because the defendant’s lawyer had failed to request a jury instruction for self-defense despite the fact that a claim of self-defense had been established at trial. The court held that this mistake was so bad that the verdict had to be set aside finding that the defendant’s attorney was “ineffective.”
The case arose out a bar fight and during the fight the defendant shot ten times into a crowd, leaving one person with a serious injury caused by ricocheted bullet that struck the foot. The defendant was a felon and was not in lawful possession of the pistol. Because of this the defendant’s lawyer thought he was not entitled to raise self-defense. It’s not clear why the defendant’s lawyer believed this to be true because Michigan’s laws of self-defense do not require that a defendant be in lawful possession of the weapon in order to raise a claim of self defense.
