Luc Ferry was the Minister of Education in France for a few years, and I looked him up to see how that went. A philosopher in government - how Platonic! I tried to find out what policies he implemented or proposed, but could only find scandals about him working at a university but never teaching and then refusing to refund his salary when they asked. Apparently his response to this was to sue accusers for libel. And then, to make his case about the importance of privacy, he told TV reporters about a former minister who sexually abused some children, and he refused to tell the public his name because personal privacy is that important (or maybe because libel laws are so strong suggesting they're a bad thing, but then why would he sue for libel himself?). Something like that.
I don't think personal privacy trumps the safety of children. Just sayin'. But from all the reports, I don't entirely understand his full intentions when he threw that out there on national television.
