The White House has released a video of President Obama calling on people in America to support changes to gun laws in the US.
The president says, "in the days since the heartbreaking tragedy in Newtown, Connecticut, hundreds of thousands of you, from all 50 states, have signed petitions asking us to take serious steps to address the epidemic of gun violence in this country.
"So I just want to take a minute today to respond and let you know we hear you."
As President Obama calls for "concrete proposals" to curb gun violence, some shooting enthusiasts have doubts they will work in practice.
A resident of Newtown told ITV News he found six terrified children hiding in his garden after last week's massacre at an elementary school.
Parents are anxious but doing their best to return to a routine, for the sake of the children.
