The data seems to suggest that the number of deaths and mass shootings sort of tracks with the number of guns, and that Finland isn't particularly better off "per gun".
In the US it’s a multi-faceted issue of mental health, lack of effective enforcement of existing laws, acceptance and promotion of gun and gang culture in music and movies, and the political utility of a continuing problem. Democrats in particular need ongoing crisis and a large dependent population to stay in power - this is why they so visibly pander to the social movement of the moment. They need the “gun issue” to stay present and emotional, they have zero solutions on iffer. Crying “Ban assault weapons!” and then being completely unwilling to define it or describe how they’d enforce it effectively just lays bare their cowardice and intellectual weakness.
