It's symptomatic of the the previous generation's propensity to look for blame and to sue.
Little Johnny came home with a tear in his trousers? It's the school's fault for letting him run !!
Although less common than the media would have us believe, it is this 'culture of blame' that schools (etc) are afraid of. Hence, playground games, outdoor activities, school trips etc are all cancelled as a result.
This culture, helped along by media hysteria has already created a generation incapable of distinguishing 'hazard' from 'risk', and of keeping a sense of proportion when informed of a risk.
Since, in evolutionary terms, man is able to appreciate hazard and risk as a result of his own experiences (and, funnily enough, not by what he reads in the papers), then we are creating a generation with no experiences on which to base their appreciation of risk. Result? Some who are scared of everything and some who are scared by nothing.
Frightening, eh?
