I really think Trump did have it a little mixed up.
He probably saw the video reports of people cheering and the video was of those overseas. You mix in your memory of TV reports and newspaper reports of cheering in the US.
It is also possible he saw the video of all of those Muslims cheering and the news reporters were talking of NJ cheering.
Whatever the case, it is not believable to claim Muslims weren’t cheering. They were and still do. They are still trying to kill us.
Was it "thousands" in NEW JERSEY? Probably not. But was it thousands? Absolutely. And were there lots in New Jersey and elsewhere? Absolutely. So who is "more correct?" The lying media that says the celebrations didn't happen at all, or Trump who exaggerated the numbers he thought he saw?
The real upshot is that Trump has successfully tied together Paris/9/11/Muslims celebrating/ and the "refugee" problem with a series of comments. Everyone KNOWS the connection. Trump has linked them without ever having to directly say it.
No matter what evidence is found, a large portion of the American people will still claim this Moslem cheering never happened. It’s the same people who will always believe “Hands Up, Don’t Shoot” in Ferguson, MO.
