Newtown Was Supposed To Change Everything. Did It?
Description:The details were beyond unimaginable.
20 children murdered inside their safe haven — their elementary school.
We heard later their Christmas ornaments were still drying on the classroom windowsills.
Six faculty members gunned down trying to save them.
We learned from police the gunman Adam Lanza shot and killed himself, but not before killing his own mother.
He used a bushmaster semi-automatic rifle that day.
President Obama promised the families stricter gun laws nationwide.(4:45)
