In Newtown, Conn., students in schools other than Sandy Hook return to class for the first time since last Friday's tragic shootings. Meanwhile funerals for those slain in the massacre continue today. 

We last spoke to Craig Whitney, author of "Living With Guns: A Liberal's Case for the Second Amendment," just before the terrible tragedy hit the news.

Now that Friday's mass killing has put the debate on gun control on the front burner, we wondered whether this time he thought it more likely that the debate will actually result in change.
