I have a friend that is dealing with some of the issues I mentioned caused by internal political disagreements between members of a shooting club.
In the US system, private organizations (without due process) are not allowed to interfere with firearms ownership and possession rights.
Violent crime statistics are subject to all kinds of interpretation and distortion. In the case of American anti-gun people, the misinterpretation is willful and destructive to our system. The last election helped stop some of this, but we must always remain vigilant.
The current (most recently published) US homicide rate is 4.5 per 100,000.

Does gun possession cause suicide (the majority of the death rate you quoted)? Of course not. A
quick look shows a rate of 7.9 suicides per 100,000 in Netherlands. That is almost twice the US homicide rate. That's right. You're twice as likely to kill yourself in the Netherlands as you are to be killed by someone else in the USA.
There is also a reverse correlation between homicide and the number of guns in our society. More guns; less crime. The drop in firearm related homicide from 1994 (7.0 per 100,000) to 4.5 per 100,000 in 2014 along with the clearance of over 68.7 million ATF / FBI NICS purchase authorizations from 2000 through 2014 would tend to indicate that firearms are being used defensively.
Detailed analysis of our homicide statistics show that quite a few are involved with young black men that are members of gangs. The violence is more intense where drug financed gangs are active. This mimics tribal behavior, and will eventually relate to a pattern seen in the Middle East in active terrorist actions.
In the case of the United States, individual citizens have the ability to defend themselves. In Europe, you will wait for a military or police response during the initial most lethal phases of terrorist actions. This is why US mass killings have all taken place in supposed "Gun Free Zones".
Homicide is not the only crime. Here, for example, is a study of the burglary rate which would indicate that suppression of defensive firearm ownership tends to lead to increased home breakins, and the potential for assaulting those inside.
Look at some of John Lott's material and you'll understand that simple statistics can't explain the difference.
As demonstrated in many places, if someone wants to kill someone else, they will choose the tool available to do the deed.
So - what system is better. You have lived in both. I have lived in the USA and spent time with relatives in Europe. I like both, but feel safer in the USA.
