Can I suggest that what happens in the US should not be influenced in any way by statistics and gun regulations in other countries? I am British, have lived there in two spells (the first from birth) totalling 45 years in both England and Scotland, plus I have had 13 years in Australia and more recently 10 in Portugal. I have never lived in the US, but believe the cultures about guns are so dissimilar that comparisons amongst the countries are of no value whatsoever.
There is some erroneous information in a few threads too. British police do not carry guns at any time on duty except under express conditions of requirement in individual situations, and a limited number of officers may be permitted to be armed. If a gun is carried by police in a vehicle the vehicle must be fitted with a special compartment in which the gun(s) are placed. My brother in law fits them for one force. I owned a shotgun in Britain (as many, if not most farmers do, and generally for pest control only) and took it to Australia with me where I bought a 3000 acre sheep and cattle station. I then bought a .243 and a .22 because the pests were much more numerous - and different to the UK. On returning to Britain I took the shotgun and .243 and had no difficulty in obtaining permission to keep them, despite not owning any land when I first arrived back. I bought 22 acres only and was able to renew the licence to have both guns. Note I had nowhere else to use them. I obtained a European "passport" for the guns, meaning I could take them anywhere in the European Union, and I brought them with me to Portugal where I am semi-retired on 16 acres. I knew many people in Australia and Britain who had guns, and I never met anyone who had any difficulty in obtaining their licences. I did not know anyone who owned a rapid fire gun of any description, they are not really pest control weapons in the farmers' sense. I knew station owners in Australia who carried a pistol in order to be able to shoot their own livestock that needed to be culled.
Rules on handguns in Britain changed whilst I was there after being in Australia and rules on semi-automatics in Australia changed after I left. I would say that amongst non-farmers it is unusual for people to own guns in either place. In Britain there is little land available for shooting, and what there is is very expensive shooting, so rich people who are non-farmers are the ones most likely to have legally held guns, plus a very few who target shoot. There is more scope in Australia, and some people in rural towns will have guns and the availability of land on which to shoot.
Neither place has a history of widespread gun ownership, and as a consequence the number of guns per head of population is miniscule compared with the US. Perhaps, just perhaps, this gives rise to less criminals using guns too, because they have not been accustomed to having them around and their victims will almost certainly not have a gun. They do make mistakes when robbing farmhouses and the odd one has been shot. Of course criminals will obtain guns if they want them. Triple R gave me a link on another thread that showed one million violent gun crimes a year are committed in the US. Britain has about one fifth of the US population so, on the same per capita ratio would have 200,000 similar crimes. Statistics are published to September each year, the latest currently available, 2011, gave just over 6,000 such crimes, a drop on the previous year of (from memory) somewhere over 7,000. There are statistics available for Australia both pre and post the automatic ban.
I would not now walk alone at night (and some parts in daytime) in any major UK city except along a brightly lit major thoroughfare with lots of people around. I saw a statistic recently that 50% of all crime in the UK is committed in the Greater London area.
What you decide to do, if anything, about further gun control is up to you, the people of the US, and foreigners should keep their nose out of what is your business. It has absolutely nothing whatsoever to do with politicians or so-called celebrities from other countries.
