BTW, a factual question need be submitted to a jury ONLY when there is a factual dispute.

Your statement is incorrect: As a general rule, the jury is responsible for determining whether the use of deadly force was reasonable under the factual circumstances, even if those circumstances are not in dispute. IMO, the judge made the legally correct decision.
