Vermont had 8 murders in 2011, with a population of 600,000 people. That's a rate of 1.33 per 100k people in a state where >40% own a gun. Germany's rate is 0.9 (with 30% gun ownership) and the Netherlands is 1.1 (with 3.9% gun ownership).
It would be interesting to take apart the eight Vermont murders in 2011, and see if drugs or alcohol played any part of each homicide.
