Well, there's always things like this, as somewhere to perhaps at least start talking about what it going on:

That said, crime statistics is a bit like the suicide statistics of the 1960's. Some countries back then got VERY high scores because suicide was NOT religiously or morally censured there, but rather seen as a psycho-social problem. While other countries miraculously reported NO suicides, except they instead had large categories of weird "accidents" that annually led to the death of a bunch of people.
The pictures formed reflect what people consider criminal behaviour AND report as such to the authorities, not directly what the laws say.
Glad you brought up suicide, which is actually one of the big problems of crime statistics, especially those involving guns. In the US, suicides with firearms are included in the overall number numbers for gun deaths, which dwarf homicides and murders. Many other countries who provide statistics on firearm violence do not include suicides in the number, hence theirs are much lower.
By and large, men use more direct and successful ways to commit suicide than women, and in places where access to firearms isn't restricted, their use is going to naturally be high. There is a gun range in town that rents out pistols to visitors. About once a year, since its been open, somebody goes there, rents a pistol and buys a box of ammo, goes onto the range and blows their brains out. Its common enough the store has a protocol for it. Close the store, send most employees home that didn't witness it, as soon as the cops finish with witnesses and EMT leave with the body they hire a cleaning service to clean up the scene, and then they reopen the next day like nothing happened. Most foreign countries that have increased gun restrictions, often to the point they're nearly impossible to find unless one is a criminal or terrorist (at which point they're not hard to find), male suicides are more often done by hanging, jumping off tall structures, etc.
Take the US crime rate, especially the murder rate. Remove the numbers from Chicago, Detroit, Atlanta, Washington DC. Suddenly the US is one of the safest places in the world. The US doesn't have a crime problem. It has a city problem.
