I hid in fear while a gunman killed 17 at my school four years ago. Why has nothing changed? | Dara Rosen

Outrage after Parkland went nowhere - children are still dying. After the horrors of Texas, US politicians must introduce gun controls

When I was a sophomore at Marjory Stoneman Douglas high school, in Parkland, Florida, a gunman entered my school and murdered 17 people. I hid in a closet, terrified that I was next. As a survivor of a mass shooting, whenever another shooting happens and gets broadcast in the media, your own trauma begins to haunt you again. And so it was recently, when a gunman entered Robb elementary school in Texas last week, and killed 21 people: 19 children and two teachers.

After the shooting at Parkland, we heard a lot of chants like never again" and enough is enough". Sometimes, it felt like we were on the brink of change, like this senseless tragedy might be the catalyst for gun reform. There was no shortage of protesters or outrage.
