This is so frightening and sad, and Turkey is the U.S's ally! Is there nothing sacred anymore? Not even a moment of silence for the victims and the families of utter brutality?
@Neil Obstat: You said, "I heard them quote a sports fan from Turkey who said that two years ago when they had a tragedy, nobody held any moment of silence for that, so why should we suddenly do it for Paris?"
Even if that were true, the crowd was "asked" to show respect in silence. Respect is something Muslims, I would hope, understand just like everyone else. Booing is clearly a provocative act.
