When in doubt there is no doubt. I'm all for evacuating when it is obviously the best thing to do. Sometimes it's obvious it is not necessary. Sometimes it's a grey area and there is doubt, often due to lack of information or accurate information in which you have confidence. In all circumstances it is your neck on the block. Damned if you do and damned if you don't. Prevaricating is not a good idea as the 'flames rise high into the night to light the sacrificial light'....
