Former FBI agent
Retired FBI Agent says bureau received ‘stacks of reports’ of calls of Muslims celebrating WTC collapse

Walter Zalisko, a former police officer in Jersey City, contacted The Fact Checker to say Farmer was wrong. He says he heard on the radio dispatch at the time that officers had found Middle Easterners “clapping and laughing” on a number of rooftops, even in one case knocking down a cardboard version of the Twin Towers. But he does not think a police report was filed. “It was at most a hundred people doing this,” he said, saying Trump’s description of “thousands and thousands” was an exaggeration.

Eyewitness account

I live in Jersey and Trump is right: Muslims DID celebrate on 9/11 in NJ . . . we saw it!

“People can be forgiven if they don’t know whether to believe Donald Trump’s claim that he saw Muslims celebrating 9/11 in New Jersey. But I, a New Yorker who was nearly killed in 9/11 and had that day burned into my memory, saw it with my own eyes. There was a video aired of the incident. I remember seeing obviously Arab-looking individuals dancing and shouting for joy on rooftops. There were less than thousands of them, but there were way more than a handful

“Matthew H. Rudd, an attorney, said he left the courthouse in Paterson midday three days after the attacks and saw “half a dozen cars full of young Arabic-looking men drove by blaring Arabic music and cheering loudly. I do not have any recordings or photos, but I can tell you that it was a very disturbing and unsettling sight.”

Here in New York, it was easy to get angry listening to Egyptians, Palestinians and the Arabs of nearby Paterson, N.J., celebrate as they received word of the murderous attacks in New York and Washington. But Mayor Giuliani (who has been tireless and magnificent in this crisis) rightly warned New York- ers that it would be wrong to take their anger out on the city’s Arab and Muslim residents. Attacks on Arab-Americans in Paterson or elsewhere are utterly indefensible. Omar, a Muslim New Yorker and former student of mine at Cooper Union, e-mailed me to say he was “sickened to watch Middle Easterners celebrate our sorrow.” He is an American who has imbibed our values while maintaining his Muslim faith. He wants no truck with those who kill in the name of Islam. ”

From the suburbs of Washington, DC, a former tenant witnesses the reaction in the Skyline Towers, Pentagon-area apartments popular with Saudi diplomats and Muslim immigrants:
“As the World Trade Center collapsed from the earlier attacks by Hanjour’s confederates, residents could be heard rejoicing throughout the complex, according to one resident who was there. “The truth is, the residents of Skyline Towers cheered that very day when the Trade Center fell,” the former tenant says. “The people in these buildings are animals.”

…” Curtis Sliwa, a WABC host also criticized by Grant, says callers told him of a celebration that “they felt was crazy, that was horrible, so we reported that based on the calls.” Sliwa went to Paterson the next day and says people told him that the cheering was done by about a dozen bicycle-riding teenagers. Paterson officials are “in total denial,” says Sliwa. “They’d rather shoot the messenger.”

A related story, for context:
“Oct. 12 — This week, I went to Brooklyn in search of an “urban myth” about the World Trade Center assault. Was word of the attack on the street before Sept. 11? What I found out was chilling—this story is no myth…
…It recounted the story of a kid who bragged around school before the attacks that the World Trade Center was going to be destroyed. On Oct. 11, Jeffrey Scott Shapiro, an aggressive young reporter for The New York Journal News of Westchester County, N.Y., published an article that tracked the story to New Utrecht High School in Brooklyn, N.Y. Shapiro identified a teacher who witnessed a freshman in her class saying the week prior to the World Trade Center attacks: “Do you see those two buildings? They won’t be standing there next week…”
…There is no doubt in my mind that the story is true. But what does it mean? There are only three possibilities. One, the youth was clairvoyant. Two, the youth, knowing about the 1993 bombing, was just venting anger in a particularly timely way. Three, word of the attack on the World Trade Center was rumored in his neighborhood and he heard about it.”
