Something which disturbs and saddens me about this, other than the probable loss of life, is the apparent unwillingness of various agencies to share information which may be of help. I'm thinking particularly of the "We didn't tell them because they didn't ask" situation with Thailand. Surely common decency should dictate that any possibly relevant information should be shared as a matter of course without having to be asked and as soon as possible after an event? I appreciate that security needs to be preserved but ways can usually be found of circumventing specific detail which might betray particularly sensitive information which the country of origin might wish to preserve.
