The pain and sorrow is still palpable.

A year has passed since a former student slaughtered 17 people at Marjory Stoneman Douglas High School in Parkland, Florida.

The tragedy inspired marches and memorials, sweeping gun laws and impassioned pleas to stop the bloodshed.

But Thursday was mostly about remembering the lost and standing with the survivors.
