Welcome to Dateline everyone, I'm Lester Holt, a new call for justice in America.

It was a defining movement of 2020 and perhaps of our time.

Police shootings, protests, tragedies that just keep happening.

Tonight, three families at the very center of the struggle have come together for the first time

united in a powerful plea for change.

Here's Craig Malvin.

2020 was a year like no other.

Testing America at every turn.

But it was the wave of police violence against African Americans last spring and summer.

That pushed many to the breaking point.

Millions of protesters poured into the streets, heartbroken and angry over what many see as a long standing pattern of police brutality.

Who do you protect?

George Floyd, Brianna Taylor, Ray Shard Brooks, Elijah McLean and Jacob Blake.

All tragically became household names in 2020, putting their families green on public display in ways almost impossible to understand and thrusting the family members into unfamiliar roles at the head of a movement.

The people watching in the streets are telling you enough is enough.

Tonight, Dateline brings some of these families together for the first time.

The siblings of George Floyd, who died under a Minneapolis police officer's need.

The father and sister of Jacob Blake, who was shot in the back multiple times by Kenosha Wisconsin police.

And the mother and son of Eric Garner, who's death from a New York City police officer's chokehold in 2014, in some ways gave rise to today's movement.

This is my family. We didn't choose this family. This family chose us.

They hope what they have to say, what many black Americans have said for decades about unequal systems of justice in America, will finally be heard.

And they especially hope the Biden administration, which takes office in two weeks, is listening.
