As a teacher, I am charged by the Government, the General Teaching Council and parents to give the safety and protection of children in my care the highest priority. How, then, when I travel by air from Heathrow with 50 teenage pupils in March, will I be able to satisfy those expectations if I allow security staff to see beneath their clothes via the new body scanning technology? Can the Government really encourage a measure which, to all intents and purposes, could make indecent, state-sponsored images of my pupils?
