The last mass shooting in Denmark before this week was 7 years ago.Same could be said about Norwegians and Danish. Mass shootings in their countries as well.
It's rubbish because you tried to equate the situation of mass shootings in the US, with the situations of mass shootings in Denmark and Norway. Whereas in fact, the situation in the US is literally thousands of times worse.Why is it rubbish? Try telling that to the families of the people murdered.
Even one mass shooting should be enough to force their respective governments to act.
The UK acted after Dunblane.
