> Aside from the paltry number of trials in the federal system, states including Pennsylvania, Texas and New York have trial rates of less than 3%. In Santa Cruz County, Ariz., there were no trials from 2010 to 2012, the report said.

The numbers are damning. It's simply not possible that police & district attorneys are good enough at their jobs to identify the correct perpetrator with >97% accuracy. Or 100% accuracy in Santa Cruz County.
