Several times now enemies will not surrender. (Greased palms)

The first issue I had was a suspect stuck in the back of the van that has evidence, he couldn’t shoot his gun, but wouldn’t surrender either. Forces to kill him since I can’t detain him.

Now, trying to S rank, Jack Adams will not surrender. He doesn’t have a gun, after flashes and beanbag rounds he’s still just standing there. Is there anything I can do to make him go down without killing him?
