The US isn't a homogeneous whole. Violent crime rates don't correlate to firearm ownership the way you think. Yellow journalism is alive and well, unfortunately.
If you bothered to read, you'd find out the correlation between gun ownership and gun deaths is not only strong for the USA as a country but also when you see the picture at the state- and town/city-level. You'd also find links to studies showing a correlation between gun control laws and reduction of gun deaths. Have a good day.
