If you ever get a chance to see a play called THE EXONERATED," I highly recommend it - heavy, but not cumbersomely so, and VERY well done. Not only true stories, but entirely in the own words of people convicted of first degree murder and placed on death row and later, released upon proof positive of their innocence.
My last project in law school was a paper in which I questioned - perhaps not very originally - whether our "justice" system deserves that name, and whether we even STRIVE very much for justice any more. This play, I'm afraid, would buttress that impression, at least in some places, Whether coincidentally or not, though, I believe at least half, maybe more, of the 10 cases portrayed were from Florida or Texas.
The great thing about being a lawyer, or for that matter a court official, in this country, is that whereas the system may not reliably do justice, one CAN make a huge difference - indeed all the difference sometimes - in individual situations.
