Read through a few more pages and I noticed that he seems to have carefully chosen which years to report in some cases. For example the page is copyright 2011, but he reports crime stats in the UK from 2002. I seems that he chose the most violent time period to report, as later information show that violence is decreasing. http://www.guardian.co.uk/news/datablog/2011/jul/14/crime-statistics-england-wales The ups and downs of the chart would suggest that crime rate is not directly related to gun ownership.
Makes you wonder what other stats he carefully manipulated in his 'comprehensive' report.
