The imam of Lahore's largest mosque refused to read Taseer's funeral prayers.

Taseer recently defended a Christian woman who was sentenced to death for insulting the Prophet Mohammed.
"He was one of a handful of politicians willing to stand up for her rights," says Waraich. "Now it seems extremely unlikely that anyone will confront religious bigotry in this country in the same way."
