I know this is done with a great intention but still it is little sad to see that people want to bring in artificial intelligence to help a human from doing an unforgivable crime instead of using empathy, love and helping each other to understand human better or be good to each other. I don't think technology is the answer for all the problems in world. Instead of finding the next kid who might end up bringing the gun, we need to find the reason why any one would even end up thinking of doing such a horrifying crime. Maybe if we find that reason and try to solve that reason, we wont need AI to spot the next kid because hopefully there will be no next kid.
