Yes, they can. Britain asks U.S. for advice on how to deal with criminal gangs of looters. The first thing you do is restore the Common Law rights to bear arms and defend yourself. America got these from its former Colonial master – we kept them, England did not. In today’s England, an individual protecting his property and his life is far more likely to go to jail than the perpetrator. That seems crazy to me, but perhaps I haven’t sipped enough tea.
