Derbyshire Local Education Authority sent a memo around all it's schools last year saying that due to the risks involved with target shooting ( i.e. none <img src="http://jsramsbottom.co.uk/bbs/e/icon_rolleyes.gif" alt="Roll Eyes" width="15" height="15"><!--graemlin:--> ) it shouldn't be considered as an acceptable activity for school trips.
Deaths by drowning, falling off mountains etc etc etc on school activities are obviously rare events which shouldn't prevent these sort of trips going ahead. Geography teachers are all trained by the SAS in crossing rivers and such like <img src="http://jsramsbottom.co.uk/bbs/e/icon_rolleyes.gif" alt="Roll Eyes" width="15" height="15"><!--graemlin:-->
No deaths or injuries from target shooting in living memory however is a completely valid reason to ban such a risky activity...
