Acquittal.
Pretty clearly, he thought he was being seduced. As you’ll see, she touches his knee, she suggests they move to the bedroom for a drink, then the mics start coming off presumably so as not to record what’s about to happen. She even ends up removing his mic instead of having him do it, which leaves her hands fumbling around near his belt. But I do think he was tucking his shirt in when he slid his hands down his pants. In fact, to my eye, the film’s editors used a bit of chicanery to make it seem like he was fiddling down there longer than he really was. Pay attention to the cuts. When his hands first disappear, we’re watching him from behind the actress. Then suddenly we’re watching him in the mirror, fiddling. Then we’re watching him still fiddling from behind the actress again.
