PROP has just published its most recent Court Monitoring Report, covering 1,612 cases observed in court visits in the four major boroughs in the spring and summer of 2017. It showed that 89.2% of the defendants were people of color and 89.1% walked out of the courtroom. The report also includes a sum of all of PROPs court monitoring work over the past 4 years, complete with informative graphs, including the examples below. The report is titled after a PROP twitter campaign, which you can find more about on https://twitter.com/GangiFromProp.
