As to guns, whilst the gun laws of 1922, 1968, 1988 and 1997 were imo unnecessary and/or stupid, the argument to bring back guns dosent wash.
Why?. Simple. The British public, contrary to recent and popular myth, have never been a gun owning public. The highest rate of ownership was 1.6m legal weapons in a 60m population in 1996, just prior to the 1997 handgun ban. The majority of the UK has never held a gun, let alone owned one. And even in ‘olden’ times, we were never gun owners.
Thats why, right or wrong, the UK public never railed against the gun laws, and even in the case of 1988 and 1997 supported the bans.
And btw, it IS legal to own guns in the UK: rifles and shotguns and certain types of handgun, as long as they are licenced.
Reports of our demise have been greatly exaggerated
