It is about a world where a person (not the main character) gets the power to kill some by picturing thier face in his head and wishing death upon them. This power is less useful if picturing the face inside your mind because you could accidentally kill another person by picturing the wrong face, so they normally look them in the eyes hence the name killer glare. So after this person proves that they exsist by killing the USA president and after they established power around the world they establish give everyone the power but it lets him and his trusted servents who killed who with it and by this point all privacy is gone his servents track them down where they are tied up blindfolded and place in front of 20 people, a jury like thing. Then a photograph of the person and everything relevnt is placed on the screen, and the jurers can decide to kill them or not. There are no repercussions if they kill them but they have to do it themselves. Also the murderer can plead their case. After all this is established the story takes place.
