Juries formed from all-white jury pools in Florida convicted black defendants 16 percent more often than white defendants, a gap that was nearly eliminated when at least one member of the jury pool was black, according to a Duke University-led study.

The researchers examined more than 700 non-capital felony criminal cases in Sarasota and Lake counties from 2000-2010 and looked at the effects of the age, race and gender of jury pools on conviction rates.
