By the time these things hit the public it's too late to prevent. Just think how hard it is to react physically to a stimulus. Someone throws a baseball. It takes years of training to be able to hit that baseball and even the best of the best are successful 33% of the time. Imagine that instead of having to control your arms to take action you have to control a whole media, government, military, gang member empire. Small quick strikes are the way to go and difficult to stop.
