British authorities are
recruiting aviation buffs to look out for terrorists and other suspicious activities. Under the scheme, "plane spotters", one of Britain's indigenous eccentric subcultures, will be issued with identity cards and a code of conduct. Plans to use Britain's vast armies of trainspotters to guard against terrorism on the railways and station platforms have not yet been announced.
This is typical "close the barn door after the horse has bolted" reaction. In the wake of 9/11, all kinds of aviation security measures are being implemented, but terrorists have a million ways to launch attacks, and they are aware of the security measures, so they're not likely to use that method in the near future.
