Trump’s outrageous claim that ‘thousands’ of New Jersey Muslims celebrated the 9/11 attacks

I remember very well news footage of Palestinians celebrating the 9/11 attacks in East Jerusalem. Arafat denounced the attacks, but the spontaneous celebrations were very real. I don't doubt that sentiment was expressed elsewhere, including in the US, but I do not remember - and it certainly would have been covered - any television coverage of such celebrating here. News cameras anywhere with a Line of Sight to ground zero were pointed that way.
Donald Trump is probably recalling those Palestinian celebrations. He badly damages his credibility and valid points he makes when he throws this kind of stuff out there.

I consider myself a decent human being and a devout Christian. We have heard the debates on Muslims being at fault for the recent tragic events through out the world known as ISIS. Donald Trump is now saying that he has proof and a video showing Muslims cheering after 9/11. This is outrageous! Although I am not a Muslims, there is no way we can point all Muslims as being involved in ISIS! Just like you have bad Christians, there are also bad Muslims. To consider all Muslims as terrorist is bit absurd! Tell me your thoughts?
