Kids are excited about getting back to school. They have the backpacks, folders and headphones that they wanted. The headphones will help drown out the screams as their classmates run for their lives with the new sneakers their mom picked up. Their jackets serve multiple purposes for warmth, style and tying a door shut so a shooter can't get in. Did you know that skateboards are handy for when you need to shatter a window for an emergency escape route? Scissors and colored pencils can double as weapons and socks are useful tourniquets when you're in a jam. A girl hiding in a bathroom stall texts her mom, "I love you," on the phone she finally got for this school year and closes her tearful eyes as the door opens and heavy footfalls echo against the tiles. The Sandy Hook Promise says that school shootings are preventable when you know the signs.
