From the July 18 edition of Fox News' The O'Reilly Factor:
BILL O'REILLY (HOST): At the top of the broadcast we were discussing the terrible police assassinations. I think it's domestic terrorism. And whether the Republican Party is going to make that issue, killing police officers, a campaign issue. Will you do that?
DONALD TRUMP: Of course. It's a big issue. It's a horrible issue. And it's going to be a very important one. It's called law and order. We want law and order. And that's going to be one of my big issues and always has been.
O'REILLY: What about the Black Lives Matter movement? Will they be singled out as a provocateur in this terrible situation?
TRUMP: Well, you see them marching and you see them on occasion, at least, I have seen it, where they are essentially calling death to the police. And that's not acceptable whether you like them or don't like them, that, Bill, is not acceptable. But I have seen it and you have seen it.
O'REILLY: When you say it's not acceptable, if you are elected president, what can you do about a group like that?
TRUMP: Well I think you have to look into it very seriously because people get themselves into big jams for saying a lot less than that. I have seen them marching down the street essentially calling death to the police. And I think we're going to have to look into that. Especially in light of what is happening with these maniacs going and shooting our police.
O'REILLY: When you say look into it, there is a constitutional right, of course, to freedom of assembly and free speech. Are you saying that you would order the attorney general to look into it for possible charges?
TRUMP: When you see something like that taking place, that's really a threat, if you think about it. And when you see something like that taking place, we are going to have to, perhaps, talk with the attorney general about it or do something. But, at a minimum, we're going to have to be watching. Because that's really bad stuff and it's happened more than once.
O'REILLY: Do you believe the group, Black Lives Matter, is a fuse-lighter in the assassinations of these police officers?
TRUMP: Well, certainly in certain instances they are. And they certainly have ignited people and you see that. You see that all over. And I think it's a very, very serious situation and we just can't let it happen. Now, everybody is free to say what you want to say up to a point. But when you are calling death to police and to kill the police, essentially, which is what they said, that's a real problem, Bill. That's a real big problem.
