Another possible place to begin would be to rigorously quantify and analyze relevant information. One example would be to examine what might be called the Mecca Metric. This is a measurement of what imams at mosques preach to congregations of Muslims gathered there for religious guidance:

What percentage of these imams preach that Islam is a peaceful religion?

What percentage of these imams preach that the September 11 hijackers violated Islam and did not go to Islamic paradise?

What percentage of these imams preach that Major Nidal Hasan, who killed 13 fellow soldiers at Fort Hood, violated Islam?

What percentage of these imams preach that the Boston Marathon bombers violated Islam?

How many imams will accept a challenge to include such a message every single time they preach?

How many imams will assist by releasing video of their weekly preaching? If imams will not do so at this time, when 30 of the FBI’s 31 most wanted terrorists are Muslim, why not?

The Mecca Metric is relevant because an Internet search for what imams say at mosques currently reveals imams preaching hatred, killing, jihad, and death to congregations of Muslims who gather at mosques for religious guidance. Conversely, an Internet search currently reveals few if any instances of imams preaching peace. I have yet to discover any imams preaching at mosques that the September 11 hijackers, or Major Nidal Hasan, or the Boston bombers violated Islam.

Note that the Mecca Metric does not include statements made to the press, at interfaith events, or otherwise to the non-Islamic public by imams or by organizations such as CAIR or MPAC. Such statements are made explicitly for PR purposes. Islam apologists often take refuge behind such statements. But these PR statements mean nothing if they aren’t repeated day after day, week after week, month after month by imams at mosques to congregations of Muslims.

Establishing the Mecca Metric can help evaluate the degree to which Islam in America is in fact peaceful. A higher percentage of imams preaching peace would indicate a higher degree of peacefulness.

Those are just two suggestions for ways to begin. There are doubtless many more. Protecting Americans from jihadist violence will be a marathon, not a sprint.
