Re: opps - Nope, Risk = Impact X Likelihood
Sure, and it's horrible for the people involved, but everyone needs to realise that government only cares about people on a general basis. If the impact costs substantially less than coping with truly exceptional weather, or being cynical, the cost of losing all the voters in the area, they're probably not going to see it as a realistic use of money. If you're absolutely, cast iron sure that this is truly exceptional unlikely to be repeated weather, then it isn't sensible to spend on it. The question is : are the projections accurate.
This is not the same as prior floods when either the money was not spent on defenses and failed precisely because of that, or worse, one particular council refused flood defense improvements as the residents didn't like the proposed visual impact : end result, the counties with improvements were fine, and the one without flooded. muppets..
