I can"t get over the amount of whinging. It takes about 20 seconds to get tested, it takes longer to whinge and argue with security about why one should not be tested. Also its a perception thing - if members of the public see pilots and cabin crew being tested, they are more inclined to follow suit without complaining, on the flip side if they see the flight crew complaining the first thing joe blow public will do is complain that its not fair why do I have to do it. (Yes I know we have ASIC's etc)
When I was a police officer we used to get pulled into the booze bus lane and tested just like everyone else. surely on duty police can be trusted not to be drink driving whilst in a marked police vehicle, we didn't complain just got on with it - yet again public perception it works well.
