The recent police shootings of African-American men in Oklahoma and North Carolina are becoming campaign issues in the race for president. Donald Trump is again pointing to New York as an example for the rest of the nation to follow, but it's a New York under a past mayor that Trump is talking up. Josh Robin filed the following report.

After more protests in Charlotte, Donald Trump laments how the nation appears.

"Our country looks bad to the world, especially when we are supposed to be world's leader. How can we lead when we can't even control our own cities?" Trump said.

What happened in North Carolina is disputed. 

Trump calls for more empathy. He also talks often of civilian-on-civilian crime, emphasizing the effect on African-Americans. He's offering a solution many in his hometown may find a curious prescription for repairing race relations.

"Look at the example that we had in New York of Mayor Rudy Giuliani, has been a tremendous person for me, a friend of mine for a long time, and a big endorser, a big, big endorser," Trump said.

Giuliani, New York's 107th mayor, is a familiar sight on the Trump campaign trail. He is credited with helping bring down crime in the city he led, often at the expense of close relations between police and the people they serve. A protest after unarmed street merchant Amadou Diallo was killed in 1999 is but one example.

Polls show Trump's well behind Hillary Clinton with black voters. And Thursday, a Trump Ohio county chair resigned after she told the Guardian website there was no racism before President Barack Obama and called the Black Lives Matter movement "a stupid waste of time."

With Clinton holding no public schedule, running mate Tim Kaine stumped in Nevada, avoiding details of the police shootings.

"These issues have to be raised. We've got to talk about them. We've got to put them on the table," he said. "They're not easy, but we can do them with a calm and peaceful spirit."

On a lighter note, Clinton's appeal for young voters has her between two ferns, on the popular Internet show.

"Well, this has been a lot of fun, Mrs. Clinton. We should stay in touch," said the show's host, Zack Galifianakis. "What's the best way to reach you? E-mail?
