Don't know where you got the US data, but It is not true according to the UCR Uniform crime report from the FBI!
I am a retired federal officer and had access to all of the DHS information as a supervisor.
Five secret passwords just to log on each day as required.
Don't think you had the same access as what I had...
Check your source.
I got the data from the link that says "Source" underneath the chart. It's the publicly available data on the FBI website. Keep in mind it's data for 2010, not the most recent data.
