It should be the beginnning of a permanent embargo of the city. No gasoline, nothing beyond food and medicine, none of the amenities of life.

[Barlowmaker]

No embargo will persuade a citizen with knowledge to step forward. No embargo will hamper the terrorist techniques of desperate killers.

An informant will only come forward when the benefit of that action outweighs the risk. In Mosul and Tikrit ... it was money that tipped the scale. Here, it is likely to be some local policeman, civil servant or businessman who are supporting the Baathists and terrorists, and decides to step forward and negotiate a plea in exchange for names, addresses and involvement.

You can't punish the populace who know nothing, you need to entice the individual who knows something.
