Convicting and incarcerating leaders of criminal enterprises often fails to close down the illegal operation. The enterprise continues because the economic infrastructure remains intact. Destruction of the financial underpinnings of crime syndicates through asset forfeiture is essential to law enforcement success.

It is not enough to ask only: "What crime?" and "What defendants?" There is a third question that must be asked at the beginning of each case: "What assets?" A careful financial investigation can lead from the street dealer to the kingpins.
