NPR's Jury Quiz

Think you know a lot about the jury system in the United States?  Test yourself with NPR's Jury Quiz with answers, which I found on the always-useful blog on juries, Deliberations.  Here's a sample question to test your knowledge:

           A: 1967
           B: 1975
           C: 1984
