On the one-year anniversary of the Newtown school shooting, NBC Nightly News profiled grieving parents, Mark and Jackie Barden, who lost their son, Daniel. Like many Newtown families, the Bardens are fighting to change gun laws in the United States, but progress is slow. So is healing. Jackie tells of the last night she spent with Daniel, how she read him a bedtime story. She still can't read a book aloud. Mark, a musician, only recently began playing music again. When asked if time really does heal, Mark responds "I still find myself trying to will this all into a dream, trying to wish it was not real."
