And or how do you prove someone's innocence if you can generate a believable, fake, crime video.

Supporting counter evidence will become that much more important.

You might be able to use this same technology to counteract this from happening.

If you generate content you would have a base to test an AI to spot actual fake content. You could use video's and pictures like these to test a learning AI to spot discrepancies, then report findings in detail.

Makes me wonder if there is a future in forensics for this type of technology.

This network was trained using an adversarial approach. What that means is that a second network that does exactly what you say was used to train the first.

They kept training until they created images that could reliably fool the discriminator. A more powerful discriminator would just be used to create better fakes.

If there were a government conspiracy to put you away, most of the time, they wouldn't need fake video evidence to convict you - just a bit of prejury by officer witnesses.

There's going to need to be some kind of blockchain-style tech that allows the source and veracity of video to be determined.

A blockchain in this case would just be a timestamping service, to prove the minimum time that elapsed since the image existed. That’s only useful if the time to create a fake is significantly more than the resolution of the chain - 10 minutes for bitcoin, 15 seconds for ethereum.

But that I only makes sense if you know ahead of time that the information will be valuable, and it only proves the age if there is sufficient hash power on the network, so a “private” blockchain would not be viable.
