After Monday's deadly bombing in Manchester, England, several commentators began invoking a familiar villain: ordinary Muslims who didn't speak out soon enough.
Among the first to cast blame was British journalist Piers Morgan, who tweeted his criticism a few days after the attack:
It's an unfortunately familiar refrain after a deadly terror incident.
Where were the Muslims? Why did they ignore the warning signs? If they only spoke out more, these attacks could be prevented, the thinking goes.
