Which, if my guess about the prosecutor's theory is correct, is why Binger followed up with questions about if it would be possible that the last fired round could possibly fail to eject, where a similar re-rack would be required to eject the empty, thus "proving" his theory about Kyle pulling the trigger prior, fail to shoot at the hapless, innocent Gaige, requiring a rerack...all disregarding that Gaige was still really a threat to Kyle, despite his fake surrender, and Gaige clearly demonstrated when he still tried to shoot Kyle.
But then the re-racking would have been shown on the video. But all that exists is Rittenhouse taking a moment to look down on this rifle.
