Even if this were remotely possible, which it isn’t, it would not be a prize.
If you think that your life and experience are not affected by external attacks, or anything else that happens in society or around the world, you are sadly mistaken. In the last twenty years or so, the various parts of the world have become so connected that everyone is affected by anything that happens elsewhere, and particularly if it involves violence.
It’s also good to consider violence in all its permutations and connections. For example, the production of toys in China affects people in my society right here in a harmful way. The increased production of motor vehicles and their use in other countries impacts the food that is available to you right here and the way you dispose of it. A hurricane made larger and stronger due to global warming impacts the migration patterns of humans and wildlife, which in turn affects you and your society, including stress on the social systems needed to accommodate evacuees and the ability to find and produce food.
If you think that violence is limited to a single crime committed by someone in a place where you do not happen to be, you might be able to fool yourself that it doesn’t affect you. But it does, you see, because then you might feel the need to avoid that place and to close your mind off to the factors that led to the commission of that act of violence. It didn’t happen to you, so why bother thinking about it? If it involved drugs and people you would consider less than human, then you can just write them off as junkies or perverts or criminal felons without having to think about them as fellow humans like yourself. But if you were to consider all the factors in their lives that led them to acts of violence, you might have to also consider that that could have been you in the same circumstances. Uh oh. That won’t do for a tough guy who doesn’t want to feel anything or think about anything in any sort of human or meaningful way, particularly if it means feeling a sense of responsibility for others and the society. And yet it certainly appears to me that such desensitization, the ability to not see and feel from a common human perspective, is exactly what’s wrong with this society and impacts the violence in it and elsewhere.
