Primary school children, and for all I know, secondary too, are having drills on school lockdown. Hiding under tables, etc, and barricading classroom doors. A teacher on the news this morning said that the children were used to it now. If you are a teacher, do you agree with this, do you find it a useful exercise or would you say that it is instilling unnecessary fear into young children, as the possibility of schools being attacked is pretty minimal? I know it can happen and has happened, but such an event is extremely rare in the UK. (I am thinking Dunblane).
