From James Q. Wilson, one of America’s greatest living political scientists.
AS FOR THE European disdain for our criminal culture, many of those countries should not spend too much time congratulating themselves. In 2000, the rate at which people were robbed or assaulted was higher in England, Scotland, Finland, Poland, Denmark and Sweden than it was in the United States. The assault rate in England was twice that in the United States. In the decade since England banned all private possession of handguns, the BBC reported that the number of gun crimes has gone up sharply.
Some of the worst examples of mass gun violence have also occurred in Europe. In recent years, 17 students and teachers were killed by a shooter in one incident at a German public school; 14 legislators were shot to death in Switzerland, and eight city council members were shot to death near Paris.
The rest of the article is a masterpiece as well, coming from the pen of a distinguished scholar, not a polemicist. I encourage you to read it.
