The MPAC report concludes that nearly a third of al-Qaeda-related homegrown terror plots since 9/11 have been foiled with the aid of the Muslim community. Saying American Muslims don't do anything to fight terrorism helps bolster the case for arbitrarily denying Muslims the same rights as everyone else, which would make it harder to establish the kind of relationships between law enforcement and American Muslims that lead to plots being foiled before they happen. There are ongoing questions about whether or not law enforcement has crossed the line with some of its sting operations -- but there shouldn't be any question that the American Muslim community has played an important role in protecting the country from terrorism.
