I think most people cheering him on expect him to get caught and probably the shooter expects that himself. Having a long term effect will be if his reasons for doing it inspires law makers to enact change. Or if he inspires 3 or 4 other people who are successful in gunning down CEOs of other exploitative industries, even after upping security. If he is killed and/or we never learn a motive, he'll just be forgotten under a pile of online and media speculation. Hopefully his plan anticipated some kind of dead man's release of his motive.
