I reckon that we should all get some perspective.
We are spending millions upon millions on airline security because a bunch of radicals killed 3000 odd people in an act of terrorism.
Tragic as it may have been, the reality is that 50000 people in Australia alone die from cardiovascular disease per year.
Add to that the rates of death and injury from motor vehicle accidents and it seems to me that the response from the government (and many other governments worldwide) is disproportional.
The reality is that even if there was NO security at an airport the greatest risk associated with flying is the drive to the airport or eating the food in the terminal!
If governments worldwide placed the same emphasis on solving some of these issues as they did terrorism and airport security the world would be a far better place - and we wouldn't have to go through the crap we have to to get to the aeroplane to do our days work.
