Earlier quoted context omitted.
Living in the Netherlands, I know that people with bad intentions most likely have guns. Even in my small hometown, a citizen that owned a spy equipment store got shot up in daylight in front of his home. Other example would be people getting robbed in their house with guns (not daily, but it happens). There are plenty of other examples... I cannot say I feel 100% save most of the time.
I have to say, you are really over exaggerating. Gun violence is just not a reality you have to be worried about here. Amsterdam is nothing like any US city where I've lived(in terms of violence on a daily basis), and The Netherlands as a whole is extremely safe.

Here you can see the gun death rate in The Netherlands per 100k inhabitants is 0.58, but there's some areas in the US where the rate is quite comparable.
What really sets things apart is the suicide rate, most deaths by guns in the US are by suicide, but there's counties in the US where there's easy access to guns and the overall death rate is lower than the Dutch gun violence + non-gun suicides.
So in a lot of cases it's not that just having guns makes everything hyper-violent. It's just that if people feel like killing themselves they'll use the best available instrument available to them.
Conflating that with general gun safety as it pertains to you feeling safe walking around Amsterdam, but not in a comparable town in the US, is silly.
