Even if there is a human who did something illegal, which I don't think is a given, it may be difficult to impossible to identify them. Look how hard it seems to be find the "vandal" that defaced the reflecting pool
Here are some ideas about the physical mechanism.
Compromise a busy ATC and instruct all the planes to land at the same time. Start a fire with some combination of ventilation controls, intentional gas leaks and the like. Maybe hijack the phones at the local fire department first. Send a train around the bend at maximum speed. Bonus points for doing it where it will cause further damage as a projectile. Cut power/gas during the heat wave/cold snap. Turn on the generator and turn off the ventilation and CO detector.
Some of these are probably implausible, but I don't think people really have a good idea of what is plausible, and there are probably more that I would never think of.
Personally though, I'm less worried about direct carnage like that than I am about having a centralized lever by which public sentiment can be invisibly steered, and concentration of wealth. Probably less killing but more decrease in quality of life and general public trust.
