On Feb. 6, 2006, three Pakistanis died in Peshawar and Lahore during violent street protests against Danish cartoons that had satirized the Prophet Muhammad. More such mass protests followed weeks later. When Pakistanis and other Muslims are willing to take to the streets, even suffer death, to protest an insulting cartoon published in Denmark, is it fair to ask: Who in the Muslim world, who in Pakistan, is ready to take to the streets to protest the mass murders of real people, not cartoon characters, right next door in Mumbai?

After all, if 10 young Indians from a splinter wing of the Hindu nationalist party traveled by boat to Pakistan, shot up two hotels in Karachi and the central train station, killed at least 173 people, and then, for good measure, murdered the imam and his wife at a Saudi-financed mosque while they were cradling their 2-year-old son -- purely because they were Sunni Muslims -- where would we be today? The entire Muslim world would be aflame and in the streets.

So what can we expect from Pakistan and the wider Muslim world after Mumbai? India says its interrogation of the surviving terrorist indicates that all 10 men come from the Pakistani port of Karachi, and at least one, if not all 10, were Pakistani nationals.

First of all, it seems to me that the Pakistani government, which is extremely weak to begin with, has been taking this mass murder very seriously, and, for now, no official connection between the terrorists and elements of the Pakistani security services has been uncovered.

At the same time, Pakistani voices are expressing real anguish and horror over this incident. Take for instance the Inter Press Service news agency article of Nov. 29 from Karachi: " 'I feel a great fear that [the Mumbai violence] will adversely affect Pakistan and India relations,' the prominent Karachi-based feminist poet and writer Attiya Dawood told IPS. 'I can't say whether Pakistan is involved or not, but whoever is involved, it is not the ordinary people of Pakistan, like myself, or my daughters. We are with our Indian brothers and sisters in their pain and sorrow.' "

But while the Pakistani government's sober response is important, and the sincere expressions of outrage by individual Pakistanis are critical, I am still hoping for more. I am still hoping for a mass demonstration of "ordinary people" against the Mumbai bombers, not for my sake, not for India's sake, but for Pakistan's sake.

Why? Because it takes a village. The best defense against this kind of murderous violence is to limit the pool of recruits, and the only way to do that is for the home society to isolate, condemn and denounce publicly and repeatedly the murderers -- and not amplify, ignore, glorify, justify or "explain" their activities.

Sure, better intelligence is important. And, yes, better SWAT teams are critical. But at the end of the day, terrorists often are just acting on what they sense the majority really wants but doesn't dare do or say. That is why the most powerful deterrent to their behavior is when the community as a whole says: "No more. What you have done in murdering defenseless men, women and children has brought shame on us and on you."

Why should Pakistanis do that? Because you can't have a healthy society that tolerates in any way its own sons going into a modern city, anywhere, and just murdering everyone in sight -- including some 40 other Muslims -- in a suicide-murder operation. If you allow that with enemies abroad, you will allow it with enemies at home and destroy your own society in the process.

"I often make the comparison to Catholics during the pedophile priest scandal," a Muslim woman friend wrote me. "Those Catholics that left the church or spoke out against the church were not trying to prove to anyone that they are anti-pedophile. Nor were they apologizing for Catholics, or trying to make the point that this is not Catholicism to the non-Catholic world. They spoke out because they wanted to influence the church. They wanted to fix a terrible problem" in their own religious community.

We know from the Danish cartoons affair that Pakistanis and other Muslims know how to mobilize quickly to express their feelings, not just as individuals, but as a powerful collective. That is what is needed here.

Because, I repeat, this kind of murderous violence only stops when the village -- all the good people in Pakistan -- declares, as a collective, that those who carry out such murders are shameful unbelievers who will not dance with virgins in heaven but burn in hell. And they do it with the same vehemence with which they denounce Danish cartoons.
