I don't know of anyone who took a headcount but on 9-11 there were enough out in the streets in Patterson NJ that folks were sent home and streets were closed off. This crap went on for days.
I know folks who live in the adjacent town, Clifton, NJ, who said the same thing about Paterson.
The celebrations were in the Main St. area from the Crooks Avenue boundary line back to St, Joe’s Hospital; also down Crooks Avenue near the intersection of Getty Avenue.
Even then South Paterson was a Muslim enclave with many Muslim businesses along Main Avenue.
People were hot about it for a long time.
After all, over 700 people from NJ died on 9/11/01.
Yes, it DID happen.
