Let us all be very glad that danger was averted this time. The fact that there was a will to cause huge amounts of misery should be the wake up call in itself. If the will is there, you can always learn how to do it "better". Of course we have to nick the people, who did it this time. However, if we do not recognise that there are people out there, who feel that way about us - and do something about those grievances - a really horrible disaster is only a matter of time.
