The same kind of misinformation has existed long before ai image generation became a thing. To increase the credibility of false narratives with a non critical audience, the video and audio only needs to vaguely resemble what is being described. They could also take a snippet from a real video recording from another place and time + real audio recording from yet another place and time, and call it good enough.
