I'm not sure this would save them in many cases. Most of the abusive content on facebook is not easily identifiable. I don't think the current AI systems are up to the task. They may be able to identify a human and a dog are in the video but not tell the difference between petting the dog or punching it.

Similarly they likely can not tell the difference between someone at a shooting range or committing a mass shooting.

Just like it is too much to expect police to stop all crime before it happens, I think it is too much to expect platforms to remove violating content before it is reported.
