Imagine how the world would be if everyone suddenly gained to ability to kill anyone they wanted just by thinking about it hard enough. What happens?
(This is an idea that could make for an interesting sci-fi story. It's an extension of the idea that we'd all be safer if everyone would carry a weapon. I wonder what ideas we on hubski could come up with... what kind of places could this story line go?)
I'm imagining a very short story.
