On r/law they explained it’s a technicians or special trial laptop thats preloaded with software like this.
Also, I'm not sure that the screenshot is of the jury's laptop. Isn't it Binger's after he turned it around to show something?
Either way, doesn't matter. Someone in the DAs office fiddled with the laptop and their laptops are loaded with this software. The DA is responsible for his office. The DA is responsible that the defense didn't get the proper copy.
