Democratic presidential front-runner Hillary Clinton said Monday that blocking Syrian refugees from entering the United States would impair the ability of police officers to connect with the Muslim community.

Clinton, who wants to import thousands of Syrian refugees, told reporters in Reno that it would look bad not to let in Syrian refugees, and that might inflame Muslims against law enforcement.

“If you’re in law enforcement, … you want the people in the communities that you are looking to get information from to feel like they want to help you,” Clinton said at a Nevada roundtable. “And if the message from people who are running for president, for example, is that we don’t want to take any Muslims whatsoever, that’s not good for law enforcement.”

“Let’s not be casting this broad, negative rejection of everybody who might be Muslim. That is not smart to protect ourselves. And I want people to understand — that is a law enforcement issue,” Clinton added.

The United States has issued a worldwide travel alert for all Americans due to heightened terrorist chatter in the aftermath of the Islamic State-engineered terror attacks in Paris.
