youtube user JWfairytale was in NYC at the time. He made a video on it, may want to msg him and ask him which one it is (he makes a lot) I remember him saying, that when people were coming across the bridge, covered in soot and stuff, the JWs inside were told to stay out of it, don't do anything.
JWs were rushing out with blankets and water anyway, despite being told not to. Just shows to me, that the WT hasn't fully destroyed the JWs consciences.
From me, this is just hearsay, so I would talk to him directly.
