Health and safety spell danger
Have you noticed that whenever there is an armed siege these days the police quickly seal off the area, surround the site with at least 20 marksmen, send for the trained negotiators and, um ...wait until the victim is good and dead before they venture in to have a peek at what's going on?
I expect that's probably a gross oversimplification ' and one which will have police commanders up and down the country in an apoplexy of rage.
