There is a lot of misinformation about gun control in the UK. This from Sky News;

"UK and Australia succeed in reform after tragedies
By contrast, countries such as the UK and Australia have succeeded in restricting gun laws after suffering their own tragedies."
That makes it sound like there were no gun controls and then after massacres there were. In fact the UK had strict gun control with the 1968 Firearms Act already. I believe Australia also had pretty effective gun control laws.
"Following the Hungerford massacre in Berkshire in 1987, which killed 16 people, semi automatic guns were banned.
Eighteen months after a gunman killed 17 people in the Dunblane school shooting in 1996, the government banned privately-owned handguns and introduced a strict licensing system."
After Hungerford semi-automatic guns were not banned, they were limited to a maximum of three rounds before they had to be reloaded. Same with the supposed ban on handguns, they were limited to single shot only and there are people who are allowed to possess handguns for self defence, such as PSNI police officers.
There already existed a strict licensing system, which was further tightened, primarily by requiring those who wanted to possess a firearm to give a reason why. Shotgun owners did not need to give a reason. All that happened is the police asked some more questions and tightened security requirements for applications and renewals.
The majority of the firearms in the UK, prior to Hungerford and Dunblane, were possessed by people who had been granted a licence by the police and had been checked and assessed as safe to own a gun. The UK was not starting from anything like the situation found in the USA, where no one has any idea who has what gun and there are millions of guns, many of which are in the hands of criminals and others unsuitable to have a gun.
The notion that the USA just needs to do what the UK did, is nonsense, since the UK had significant gun control all across the country prior to any of the mass shootings, whereas the US has many federal and state laws, that often contradict each other and it has a huge pro firearms lobby that has never existed in the UK.
