I was just on a jury and we ended up not only being deadlocked, but being chided by the judge afterwards for not being able to settle on an obviously guilty verdict. The problem, the judge said, was that people are too influenced by television and the proliferation of shows like C.S.I., where the evidence is conclusive and overwhelming. In real life, this is not so and the function of the lawyers is not to prove a case beyond any reasonable doubt, but to prove it beyond a reasonable doubt. Reasonable is the key word here. One's sense of reason should not be affected by whether the case is murder or theft, whether the penalty is jail time or death. 99% is more than reasonable. 90% is probably reasonable as well. Did he definitely do it? No one saw him, so we'll never know. What the jury rightly found was a great probability that he committed these murders, great enough to be beyond a reasonable doubt. It's a very tough decision to come to and these people have to live with it for the rest of their lives. They were there, in the court-room. They debated this for hours and you have no idea the depth of their discussions or what they picked up by being there in the first person. Their decision should be respected.
