A Florida judge has given former teacher Debra LaFave an exemption from her probation conditions to permit her to appear on NBC's Dateline. She is to be interviewed by Today co-host Matt Lauer in Tampa, FL where she is serving a three-year house-arrest sentence, after pleading guilty to charges related to her sexual encounters with a 14-year-old student. Her attorney, John Fitzgibbons, told the Associated Press Wednesday that LaFave wanted to discuss her "bipolar illness" so that others might understand her conduct.
