Technically, it's a company. At least as much as the ChiCom businesses who run similar operations in the Port of LA and the like.

Dubai-although densely-populated-is not exactly a teeming, unmanageable metropolis, a la Karachi.
When the ISI makes an excuse for why they can't locate a top-ranking Al Qaeda figure in a city like Islamabad or Karachi it at least has some plausible deniability.
On the other hand, I don't see how a undemocratic monarchy-the size of a postage stamp-with an extensive internal security apparatus can not be held responsible for the transshipment of illicit narcotics, nuclear contraband, sub-Saharan slaves, and Eastern European prostitutes, in addition to wire transfers from Islamic terrorists.
When Pakistani officials say they don't know where Dawood Ibrahim is it might very well be a lie, but it is a somewhat believable lie.
On the other hand, how do you explain Dawood Ibrahim's ability to operate his terrorist criminal syndicate-with relative impunity-out of Dubai for so many years?
