You are correct, my main point was that the owner of the shotgun was not charged at all, I should have chosen my words more carefully. However the fact remains that despite Dunwater's assertions, using a legally held firearm in self defence is allowable. There are other examples of this in recent times but unfortunately a simple search results in reams of Tony Martin articles who of course was jailed for shooting burglars but he used an illegally held shotgun.
It is very easy to make broad assertions. What I have tried to demonstrate in my replies to this thread is that every circumstance is different and the outcome depends on several factors - the precise circumstances, the law, the opinion of the CPS as to if a conviction is reasonably achievable (and in the public interest) and finally the jury on the day.
While it is a long, long way from clear, the law and the body of case law surrounding it
strongly suggests that the use of a firearm in self defence can only be reasonable in so exceptionally narrow a set of circumstances as to be practically non-existent.
ANY pre-meditated action on the part of the person doing the defending is
ENTIRELY unsupported by the law. If you deliberately set out an item such that it is readily available to you should the need arise to defend yourself then you are, as far as the law is concerned, no longer acting reasonably. This is why items in the UK cannot wisely be marketed for self-defence. You may buy a reinforced umbrella because you are sick and tired of inferior umbrellas breaking and then use that umbrella to defend yourself should you be attacked while carrying it. You would be doing so without risking the pre-meditation aspect of the law (save, perhaps, if you were carrying it on a hot summer's day with no prospect of rain). You could not rely on the same being true had you purchased a similar umbrella marketed as being for self-defence.
Given the legal requirement that all of our firearms are to be kept as secure as practicable, I return to my earlier statement where I asked if it was reasonable that (crucially!)
in the heat of the moment and faced with immediate danger the instinctive thing to do would be to retrieve the keys to your cabinet from their hiding place, go to the cabinet, unlock it, retrieve a firearm from within, load it and then take aim at the assailant, all while believing that it was a necessary, reasonable and appropriate use of force given the prevailing situation and that no other lesser course of action would suffice?
Would you trust the course of the entire rest of your life to the examination of those circumstances after the fact?
Personally, all of my belongings are insured and nothing I own is worth enough to me to trade my life for - either through death or through prolonged imprisonment.
