JUDY WOODRUFF:

We return to the events in Dallas and the violence involving police across the country this week.

And we get the perspective of the presumptive Democratic presidential nominee, Hillary Clinton.

We also invited Donald Trump. He declined, but we hope to talk with him soon.

I spoke with the Secretary Clinton a short time ago.

Welcome, Secretary Clinton.

As I talk to you, we're hearing about still more attacks on the police in this country.

Why do you think it is, more than 50 years after the height of the civil rights movement, that we're seeing events in this country like what we have witnessed this week?

HILLARY CLINTON (D), Presumptive Presidential Nominee: Judy, I wish I could answer that question. I have thought so much about it.

And I'm not sure of all the reasons why we are witnessing this kind of violence. And we have got to look at it broadly. What happened in Dallas, what's happening to other police officers in our country is absolutely outrageous.

We have got to do much more to protect and respect the police. And we have to do much more to make sure that citizens in our country, particularly African-Americans, feel respected and protected by the police.

I think we have got to listen to each other. We need a conversation. White people need to be listening to African-Americans about what it feels like to live with, you know, fear and anxiety, to be profiled, to worry about what will happen to their children when they go out to play or out on a date or go for a drive.

We have to listen to the fears of our police officers, who get up every day and do a dangerous job, like the police in Dallas who ran toward the shooting when it broke out after a peaceful protest.

I'm going to do everything I can in this campaign to try to find common ground, bring people together. And I have got some specific ideas about what we can do for criminal justice reform. We need national guidelines about the use of force, particularly lethal force.

We need to work with the 18,000 police departments in our country, some of whom are real models and others should be learning from about how they de-escalate tension, rather than turning a routine traffic stop into a killing.

And, of course, we need to investigate the implicit bias that, unfortunately, too many of us still have. And when it's an implicit bias in a police officer, it can lead to an escalating situation.

So, we have got work to do. Certainly, our elected officials, our leaders in our communities, but really all of us as Americans have a stake in trying to listen respectfully to each other and, you know, really try to find ways we can contribute to ending this violence that is stalking our nation.
