There's a disputed drone video footage where some think they see Kyle raising his gun in his left hand, but if you look at the video, the pixels they're pointing at exist before Kyle even reaches that point, meaning it can't be a gun. It may be a mirror or some other part of the car.
This is a major dispute because the prosecution gave the defense a low-quality, strange resolution rip of the video while having a higher-quality version for themselves. They admitted that "our version is better" in open court, before backing off to claim it's "just playing weird."
Kraus, who said he would have a much better job if he knew this encoding stuff, was seen with Handbrake installed on his laptop. The program was installed shortly after Kyle plead guilty according to the dates on the file.
That charge was dropped because Kyle was not carrying a short-barreled rifle.
However, ADA Binger did take Kyle's rifle, pointed it at the jury without checking it (saying his assistant had), and had his finger on the trigger while doing so.
Thankfully he didn't go full Baldwin, because there was no clip and no round in the chamber and the judge made them check it afterwards, but you can watch the stream if you want to see how it went down.
