When students in Philadelphia head back to school after Christmas break, there will be a new feature: condom dispensers. The city is installing them in select schools because of a rising rate of STD's. In fact, of new HIV cases in Philadelphia, a quarter of those diagnosed are teenagers. The city says it's serving as a partner with parents in promoting safe sex; critics, though,say this crosses the line and should be the parents' responsibility. What do you think?
