Your argument is disingenuous at best...you are cherry picking to come up with your lop sided figures. You want to use per capita when it suits your argument, then make broad claims when the per capita figures don't...for instance there was a popular meme some time ago comparing US and England crime stats, and the Daily telegraph stated that the numbers were over 2,000 per 100,000 violent crimes in England vs. under 500 per 100,000 in the US...Politifact looked at this and decided that the stats were an unequal comparison largely because of the way the different countries calculated their numbers, much like you attempt with your arguments. But, they looked at the numbers and compared them closer to like categories and came up with this....
"The FBI’s Uniform Crime Reports defines a ‘violent crime’ as one of four specific offenses: murder and non-negligent manslaughter, forcible rape, robbery, and aggravated assault." By contrast, "the British definition includes all ‘crimes against the person,’ including simple assaults, all robberies, and all ‘sexual offenses,’ as opposed to the FBI, which only counts aggravated assaults and ‘forcible rapes.

We looked at the raw violent crime numbers for each country, using statistics for England and Wales for 2012 and for the United States for 2011, in a way that sought to compare apples to apples. (We should note that the United Kingdom includes Scotland and Northern Ireland, but the numbers in the meme appear to be based only on crime in England and Wales, which are calculated separately.)
For England and Wales, we added together three crime categories: "violence against the person, with injury," "most serious sexual crime," and "robbery." This produced a rate of
775 violent crimes per 100,000 people.
For the United States, we used the FBI’s four standard categories for violent crime that Bier cited. We came up with a rate of
383 violent crimes per 100,000 people."
Social media post says U.K. has far higher violent crime rate than U.S. does | PolitiFact
So, while it certainly is not 4 times the rate in England v the US that the original meme tried to put forth, it still comes out in the apples to apples comparison with England being a more violent country than the US. So, when wringing your hands over OUR gun laws, maybe you'd do best to consider your own violent crime....Clearly, your country is more violent, and less safe for the average citizen than the US.
