Many Mooslims in NYC cheered when the Twin Towers were destroyed.
I saw one of them laughing about it, not five minutes after I had to get off the stopped train at Kingston-Throope and walk through downtown Brooklyn to see what I could do to help, either giving blood or helping dig, or whatnot. Saw this huge Black Muslim guy, just belly laughing and talking on his cellular about how wonderful it was that both buildings were down.
