Here is a link to another juror interview, Jennifer Ford, Juror #3, and the basic message Ford leaves is "How can you punish someone if you don't know what they did?" She said repeatedly that she didn't know that Casey was innocent, but the State did not prove she was guilty, and whatever bad behavior Casey exhibited, it is not evidence of guilt. Ford also said that George did not help the State's case, and at one point she said he was dishonest.
Nancy Grace predicted that if any jurors speak out, they will do so only in delicately placed situations and will be given only soft-ball questions. No they haven't been the kind of hateful pounding-on-the-table drills that drive people to suicide, so maybe that is what Grace meant by soft-ball questions.
I really feel for jurors in these high profile cases where they don't have solid evidence one way or another -- they truly can't determine if the person is guilty or innocent. But in these situations, the Law and moral justice demands that they acquit. For doing that, this jury has my utmost respect.
