Have a clearly defined definition of the word "Weapon" to be used in Law.

Through all current Firearms legislation there is use of the word "weapon". If a weapon is any item used for the purpose of visiting injury upon another then, surely, to employ an "Air Weapon" as a weapon would contravene current legislation. Some may argue that guns were designed specifically to be weapons. This is true but so were the javelin, the discus and the shot.Sports departments, in schools, don't store these in a "Weapons Store" though. Our shooting club uses firearms not weapons.
