School shootings: Sandy Hook parents' terrifying back-to-school video warning
It shows children how to defend themselves.
The families of children killed in the Sandy Hook mass shootings have issued a chilling video, showing how "back to school essentials" can be used to survive a school shooting.
The video starts out with children showing off their new bags, folders and headphones as they prepare to go back to school.

But things start to change when the boy puts on his headphones and fails to see people behind him running from gunshots.
"These scissors really come in handy in our class," a young girl says while holding them up in defence, another holds colouring pencils high as a way to deter a shooter.
One girl uses her new pair of socks to dab at a bloody wound of a friend, while another girl got a new phone so she could text her mother as she hides in the bathroom.
It ends saying "school shootings are preventable if you know the signs".
In December 2012, Sandy Hook elementary school in Connecticut saw the loss of 26 people, including 20 children aged between six and seven years old, and six adult staff members.
"We don't want people to turn away from it, so pretending it doesn't exist is not helping to solve it," said Nicole Hockley, whose six-year-old son Dylan was killed at Sandy Hook.
"At the end, the girl with the phone gets me every time," she told NBC.
This year, by 19 September - the 263 day of the year - there had been 302 mass shootings in the US, according to the Gun Violence Archive.
