A woman in America has given her nieces door stops to keep in their backpacks in case of another school shooting.
Katie Cornelis, of Conneticut, says putting stops underneath doors ‘can be powerful in keeping you safe’ as it can buy you moments of safety.
Cornelis said she first gave her nieces the door stops after 26 people were shot and killed at Sandy Hook Elementary School in 2012.
But she then shared her advice on Facebook after 17 people were killed at Marjory Stoneman Douglas High School in Parkland, Florida on Valentine’s Day.
Her post has been now shared more than one million times.
She wrote: ‘After the Sandy Hook shooting, I gave both my nieces this little door stop to always keep in their backpacks.
‘It truly pained me when I handed it to them, and I didn’t want to scare them, but it was out of love and they understood.
‘In light of the recent shooting, I wanted to share this with all parents…and ANYONE else for that matter…to get themselves one (I always carry mine in my purse).
‘Sure it’s small, but it can be powerful in keeping you safe if you ever have to barricade yourself in a room.
‘If a gunman shoots out the door lock it will still keep the door from opening and may just buy you some time.
‘I’m really sad posting this but a security expert shared this tip with me so I wanted to pass it on. I pray no one ever has to use it.’
