"Mind you of course, we in the UK haven't gotten quite so hot-headed about this security stuff as the US has "
I think this is because the UK has lived with the threat of terrorists for many years. The attack on LHR with mortars was the work of the IRA, and even though they planted bombs in all sorts of places the British public learned to live with the threat and the security it brought with it. (Police searching hand bags as people went into Harrods? Even of little old ladies....The IRA could be inventive when it came to couriers...) In the US we have not had to deal with something like this until 9-11. It will take time for us to figure out how to do security properly and for the public to accept it. (Of course learning from the Brits or Israelies would make too mcuh sense. It is fun to reinvent the wheel! arrghh)
How can the security service of an airport or even the military for that matter police the whole perimeter of every airport ?
the simple answer is they cant ! .. "
Spot on. No security, even in a totalitarian state, can provide absolute security. So you have to use common sense. Providing a designated spotting area where the public can be watched and controlled is one idea. But that can be limiting to us photographers. (I LIKE standing on top of the Queens Building and shooting arrivals....right into the sun. Musta been set up by a woman.
As spotters, photographers, anoraks, it is incumbant upon us to promote our hobby and at the same time pay attention to security concerns. I hate the idea of spying on one another, but if I feel suspicious about the guy with the Stinger instead of a Sigma I will call someone.
