Trump vows to crack down hard on protests to prevent European-style unrest

"You know, these people are crazy... This is exactly what we've seen over the last 3-4 days, with such lunatics destroying their country in France. We, by the way, are not going to tolerate this... If there's a potential threat, I hope you won't mind if I deal with them very, very harshly — because that's exactly what I'm going to do. Then they won't be able to destroy our country."
