Still developing tonight.

Four people are dead, including a child after a shooting in Southern California.

I mean, a lot of people hear about random acts of violence, mass shootings, the media sometimes makes it sound very inevitable or episodic.

Now, most Americans are alarmed by the level of gun violence in our country.

But what to do?

Brian Malte, chief executive officer of Hope and Heal Fund a gun violence prevention organization, said We first need a clear understanding of the problem.

We do know that mass shootings and public mass shootings are on the rise.

What the media misses a lot is most mass What the media misses a lot is most mass shootings are related to domestic violence.

The availability of guns.

That's the other part of the question, right?

That's more of K through 12 shootings.

85% of those shooters get their guns from the home.

Those are obviously accessible.

California has a law called gunman's restraining order.

If you see somebody who might be a risk of hurting themselves or others, that gun can be temporarily removed from that person.

There's a lot of warning signs for someone who's going to conduct a mass shooting.

I'm seeing a big sea change in the way national organizations are looking at this issue, what some refer to as CVI, which is community violence interventions, where folks who have lived experience but have now reformed themselves and now want to reach out to younger, mostly men that look like them, to say there's a different way.

Jose Osuna, a civil service commissioner with the city of Long Beach, says he committed violent acts as a young gangbanger.

His son was killed at age 17.

Now he advocates for violence prevention.

My vision for the future is very lofty.

It's big.

It's huge.

It's a world where we as human beings choose not to harm one another.

Well, Jose's vision is one we can all share and work toward.
