Is it true?  Is our criminal justice system broken?

I stumbled across the graph below doing some research.  Judge for yourself.  

My own view is easy to state.  The claim that the criminal justice system is broken is not just misguided or poorly informed.   It's a point-blank lie.  The number of victims of violent crime aged 12 and over, per 1000 population, has dropped by two-thirds in one generation.  That is a spectacular success by any conceivable measure.  Whatever we're doing, we should do more of.
