"Two mosques in Paterson, New Jersey, where Saipov lived, said they have been receiving threats since the attack. The Islamic Center of Passaic County said it has gotten eight telephone threats to burn the center down and kill its occupants, prompting extra police patrols."

Why didnt this "news story" report that there's documented evidence that Saipov ATTENDED the same sketchy mosque in his neighborhood that was probed by the 911 investigators?

What motive would the liberal media have in not reporting that, other than to lessen Saipov's true source of radicalization?

It would be akin to the media reporting that NAMBLA headquarters was threatened after a pedophile rapist who lived nearby was arrested, but then conveniently left out the fact that that pedophile was actually a member of NAMBLA for years.

Sometimes what the media leaves out of a story is more damning than what they put in.
