Donald Trump confronts audience after he gets booed at debate

Republican front-runner Donald Trump responded to audience members who booed a comment about his strategy to deal with the Islamic State group.

Trump was booed while sparring with US Sen. Rand Paul (R-Kentucky) over his proposal to crack down on parts of the internet to combat terrorism.

"If you're going to close the internet, realize America what that entails: That entails getting rid of the First Amendment, OK?" Paul said. "It's no small fete."

Trump said Paul was exaggerating his position.

"As far as the internet is concerned: I'm not talking about closing the internet," Trump responded.

"I'm talking about parts of Syria, parts of Iraq, where ISIS is. Spotting it. Now, you could close it," he continued. "What I like even better than that is getting our smartest and getting our best to infiltrate their internet. So that we know exactly where they're going, exactly where they're going to be. I like that better!"

The audience then erupted into cheers and applause with some loud booing mixed in. Trump was puzzled.

He then lectured his hecklers.

"I just can't imagine somebody booing," Trump reflected. "These are people that want to kill us, folks. And you're objecting to us infiltrating their conversations? I don't think so. I don't think so."
