People forget we do not have a Second Amendment in the UK and have no inherent right to possess firearms. Its by the good grace of the Chief Police Officer.
Despite what was stated by that 'here today gone tomorrow' Police Minister Damian Green (sacked in 2014) in his introduction to the HO Guidance, there are many who would disagree that it is a 'privilege' to lawfully possess firearms - and it doesn't matter how many times certain police departments keep parroting it - the fact remains that it is a right, albeit one that is conditional on certain criteria being met.
A position supported by one or two big guns in the shooting world:
"The British Shooting Sports Council submission to the Parliamentary Select Committee on Firearms Control included this:
Gill Marshall-Andrews is not correct when she states that gun ownership is a privilege, not a right. Whilst it is reasonable to assert that the right to have arms which existed prior to 1920 has been circumscribed, elements of that right remain in current legislation, viz. Section 27(1) "A firearm certificate shall be granted where the chief officer of police is satisfied…" and Section 28(1), "…a shot gun certificate shall be granted…" Whilst the conditions that follow are stringent, the term "shall" is used rather than "may". This is not accidental and arises from recommendations of the Blackwell Committee of 1919.
BASC's included this:
5.3) BASC does not agree with the proposition that the ownership of firearms
for legitimate purposes by suitable persons is a privilege. We assert that it is a
right, albeit one which is conditional upon certain legally defined criteria
being satisfied. The language at Section 27(1) of the 1968 Act sustains this; “A
firearm certificate shall be granted where the chief officer of police is
satisfied...” and Section 28(1), “...a shot gun certificate shall be granted...” The
term ‘shall’ is used rather than ‘may’, as is the case in Northern Ireland where
the Chief Officer has absolute discretion. The use of the mandatory word
“shall” is no historical accident and comes from recommendations of the
Blackwell Committee of 1919."
Are you familiar with the Blackwell Committee's Report and subsequent legislation?
