Hell yeah cos after all we all know how many flights have been placed into jeopardy by 70 year old ladies with crochet needles! A far more reliable indicator would be to ban anyone with a beard. At least that would perform a public service keep that idiot Oakeshott from flying to Canberra to commit more innocent stupidity.
All these scanners are a joke, a public facade to make listeners of talk-back radio feel a sense of false security.
I'd like to know what triggered this world outbreak of nonsense where the sad and the badly dressed decided that all risk can be eliminated without ever considering the human, economic and emotional cost of attempting such folly.
If, as humans, concentrated the same effort on, elimination of ignorance and stupidity, as we do on painting things day-glo and promoting dumb legislation, then this world would actually become a better place.
