Just over a month ago, a lot of parents -- including many at TODAY -- were talking about the New York Times piece about the controversy that has become letting a child walk to school. Now the tragic murder of 7-year-old Somer Thompson, who vanished during her mile-long walk home from school, has us talking about the safety of our children once again. What do you think? How much freedom do you give your child? Has the case of Somer Thompson changed your opinion about allowing your kids do simple things like walking to school or playing alone in the yard? How do you talk to your children about strangers who may approach them when they're on their own? We'll be talking about these on Friday's show.
