Ross, what you have said makes complete sense as per usual.
Who in their right mind would venture onto streets when the mayhem we have seen on the TV is going on.
Why should the vast majority of people have their lives and business ruined by the rioters and looters, when mobile signal blocking might stop the large numbers of thugs that appear when called.
Most businesses have landlines and people did manage to run their lives prior to mobiles, I am sure the vast majority could go without chit chat for a few hours and there are public telephones and neighbours if needs be.
