Currently eyewitness criminal sketches are still drawn by artist so they are naturally low fidelity.
That will change once you can generate a photo of a face (like https://thispersondoesnotexist.com/) based on your brain waves.
This will be disastrous on so many levels. The eyewitness might not have a good sample of a minority race. The GAN dataset itself might also only be trained on celebrity faces so it doesn't know how to generate anything else (e.g., a teen).
But it will be deceptively high resolution so police will rely on it.
If you have a generic face your life is fucked.
