The authorities had to get a conviction (at the second time of trying) otherwise all the current security in place would have been called into question. There would have been a complete loss of face. However they must not now rest on their laurels. I have always thought that the most glaring hole in aviation security is the suicide bomber. If a man is prepared to die then what is to stop him boarding with a hold suitcase, with these selfsame liquids placed inside.? I believe profiling is the way ahead with an absolute requiment that tickets are bought at least 48hrs before flight with either a card or cheque but not cash.
