More from the Boston Globe:

Yusufi Vali, executive director of the Islamic Society of Boston, which runs the mosque, said Tsarnaev told the speaker, “You are a kafir [an unbeliever],” and said he was contaminating people’s minds and was a hypocrite.

Vali said, “The congregation then said, ‘You are the hypocrite.’ The congregation shouted him out of the mosque.”

Shouted him out of the mosque. Of course it still won’t be enough for some people.
