A decent point, I made it halfway through the video.
However, when compared to mature western democracies, you are well out there.
If Americans wish to compare themselves with central American countries, with an unstable government, rampant poverty, endemic crime, and failing criminal justice systems yes it is doing fine.
However, id put America in a similar class of countries as German, UK, Australia, France, Japan and South Korea. When compared to its peers America does very badly in this regard.
Crime and homicide are complex issues much more complex than guns/no guns being the only factor. However to my mind failing to acknowledge and act on one factor that would have a significant impact on the safety of citizens, whilst also looking to address the others seems shortsighted at best.
