We already have them here but American thugs have an American style. We call them Flash Mobs and there is no resistance to them. No looters have been shot by gun-possessing Americans. They form, do their destruction and looting and leave before police respond and store owners do not resist them nor do any armed bystanders. The Sikhs and Hindus in Britain and the Koreans in LA show up the Armed Americans pretty handily.
You’re wrong about that. Armed shop owners WOULD resist if what happened in Britain happened here.
