When someone points a gun at you, you do what they tell you whether they are wearing a badge or a mask. What security could the restaurant put in place? As much as banks have target hardened their premises, there are still bank robberies. The only practical solution would be to have armoured glass separating the staff from the customers, with airlock type serving hatches. Hardly the sort of welcoming environment for the customers in which to relax and eat. 'Drop box' cash safes of the type often used in petrol stations, prominently displayed as such in the public view would be about the only viable deterrent, as it would make the place not worth robbing (no keys on the premises.)
And just what good are security guards going to do in such circumstances? They're not bullet proof. Technically they may be able to carry batons and the like, but only a fool takes a stick to a gun fight. Jeff Cooper's first rule of gunfighting "Have a gun."
“I’m glad they have accepted liability however I’ve decided to move away from Liverpool now as I just don’t feel safe anymore. It’s such a wonderful place full of amazing people but I feel I need a fresh start.”
Perhaps she should also sue the city council, the police, and if the robber is ever found, the social services department that so terribly failed him. There is, I think, a clue to the whole set up.
Still, at least if the robber is caught, his firearms licence is certain to be revoked.
