You have said several times that you don't know much about England yet regularly post statements you've found on google as if they were facts. Unfortunately unless you do a very full search you're misunderstanding.
I live in Northumberland, North of Newcastle so in the area you incorrectly state has a higher violent crime rate than London, I also have a friend who's been a serving armed policeman for 20 years and another now retired who was a senior training officer for Northumbria armed division so I hear first hand what they face on a day to day basis.
The year up to March 2019 saw a 4% increase in gun crime in the UK but that total was still less than 10,000 in a population of 60 million.
I suggest you look at the gov stats and other sources if you want the real picture as many other sources you will find combine overall crime which includes all the relatively minor stuff like pickpockets, shed break ins car thefts etc rather than serious violent crime and in the latter case you are far more likely to be stabbed with a kitchen knife than be threatened by a gun in the UK.

Gun crime remains rare in Britain.
In England and Wales in 2016-17, there were 31 fatal shootings - or one for every 1.9 million people. And there were 9,578 weapons offences that resulted in injury.
In the US, in contrast, there were 11,000 murders or manslaughters involving a firearm or one death for every 30,000 people.
There are particular hotspots in the police force areas that cover large urban centres.
London had the most firearms offences per head of population, followed by the West Midlands force area, covering Birmingham, West Yorkshire, covering Leeds, and South Yorkshire, serving Sheffield.
Last year: just over half of all firearms offences involved a gun actually being fired, in just under half of cases, a gun was used as a threat, in a small minority of cases, a gun was used as a blunt instrument

Figures released by the Office for National Statistics (ONS) show that 9,787 crimes were committed with firearms in the year leading to March of 2019. The number of offences has risen by four per cent over the previous year and twenty-seven per cent in five years, the latest statistics available show.
Young people represented the majority of the victims, with 56 per cent aged between 15 and 34 years old. Most offences were committed in densely populated urban areas, with just five city police force areas representing 58 per cent of all recorded instances; the Metropolitan Police, West Midlands, West Yorkshire, Greater Manchester and Merseyside.
Thirty-three people were killed in firearm-related instances, three more than the year before, according to the ONS.
Gun seizures have dramatically risen in the UK, with The National Crime Agency (NCA) reporting that in the past ten months alone 425 guns have been confiscated, compared to 104 guns in 2017/18, per Sky News. The fourfold increase is attributed to smugglers from Europe bringing the weapons to the UK.
