There have been several cases in the UK in recent times of Official Action preventing people being rescued for 'Elf and Safety reasons. Here is just one example:-
"This was Walpole Park in Gosport, Hampshire, on an overcast lunchtime last March when no fewer than 25 members of the emergency services, including a press officer, descended on a 3½ft-deep model boating lake minutes after Simon Burgess, 41, fell into the water when he suffered a seizure. But as an inquest heard last week, he lay floating face-down for more than half an hour while firemen, police and paramedics watched and did nothing."
