The New York Times has an article, published today, about the growing phenomenon of jurors accessing the Internet during a trial. A federal drug trafficking trial in Florida was declared a mistrial after 8 jurors admitted they did research about the case on the Internet using their iPhones. A similar case in Arkansas overturned a $12.6 million civil judgment after the judge discovered a juror was posting details about the case on his Twitter profile.
