To be fair Chollie, there is a certain poster who just likes to attack people who support security. And the moderators allow it. Fortunately, this individuals generation is dying out - so hopefully we won't be subjected to it much longer. Meanwhile, bad guys will evolve with science as they invent new ways to bring aircraft down. Security needs to evolve as they do. People who don't want to evolve will just die from being miserable and hateful all the time.
