To avoid these issues it is imperative to hold natural and legal persons responsible for the software they use, just as it has always been, regardless if it is using anything artificial intelligence-ish. Under that rule there will always be a way to handle problems arising from AI. Without following that rule, pretty much nothing else matters. In the case of the mass-shooting prediction: Good luck proving that it is accurate enough to legitimize punitive consequences for the suspected perpetrator, and without violating a half-decent democratic constitution. Some of the predictors are in themselves crimes, and picking those up would justify correctional measures, no problem. Schools and police also need to get a lot better at picking up and handling mental health problems, be it through algorithms or smarter laws and procedures. Make it easier for the mentally ill to get medical help than to buy an assault rifle, for starters.
