People like Luigi remind me of “The Children of Kali” from the book “The Ministry for the future”. The Children of Kali targeted the owners of these multinational death machines but would not accept any collateral damage. Instead they were patient. The abusers got so scared they would never leave their house, but even that would not save them. Point is, these people follow a set of laws different from the ones that dominate society. They conducted themselves according to that law and that guided their assassinations. Something to think about as our own laws become lawless.
