marct, I don't know but as you say it would be easier to understand as a system, but that is part of the problem with these guys they act alone, but are good at recruiting Innocent people to help them without there knowledge. But the process or method of operation is actually called "telling a story" they make up whole scenarios in there head and they just keep adding to it, they often write them down or document them in some way until they reach the breaking point. Another thing is there are a lot of similarities between stalkers and suicide bombers especially the rituals they go through before they commit the attack, often spending the night in the graveyard before the attack.
