Yes, but what about clarification

Can I deliberately keep a weapon, say a baseball bat or a household knife, in a suitable place so that if I am woken in the night by a burglar the weapon comes easily to hand? If I use this weapon on the burglar will the fact that I had premeditated access to it be used against me or considered in any way whatsoever when deciding if I should face prosecution?

Those two questions are simple enough and important enough to warrant clarification. Yet, the recent publication by the Crown Prosecution Service which attempts to teach misguided householders their rights fails to do so.
