You can't compare countries because they're too different.A car owner is also not automatically the cause of an accident. Nevertheless, more cars-more accidents. More guns-more dead.
If more guns=more dead why so few people are killed at rifle ranch, police stations, gun shows, military barracks? there are the most guns
I'm talking about privately owned guns. But you're welcome to buy guns and kill each other. I don't live in the USA and don't want to go there. Definite end of the discussion.
In germany most guns are shot at ranch with private guns. At german championship there are thousands of armed people with their own private firearms. Nobody ever got killed there.
