If Joe public would stay out of an airports for a while, using other means of transport, this nonsense would be stopped soon!
The commercial pressure would change there minds!
Just imagine the picture when from tomorrow the airports are empty and all the so called "security staff" hanging around and twisting there thumbs?
No car drives into the NCP, no business is done in the shopping mall "Airport".
What you think, how long would that be accepted before things will change?
BAA needs your money too, and as we know, money rules the world!
