This sounds like an incredible book:
On the financial incentives implicit in the War on Drugs:
In fact, the Times reported that police departments had an extraordinary incentive to use their new equipment for drug enforcement: the extra federal funding the local police departments received was tied to antidrug policing. The size of the disbursements was linked to the number of city or county drug arrests. Each arrest, in theory, would net a given city or county about $153 in state and federal funding .... As a result, when Jackson County, Wisconsin, quadrupled its drug arrests between 1999 and 2000, the county’s federal subsidy quadrupled too .... Suddenly, police departments were capable of increasing the size of their budgets, quite substantially, simply by taking the cash, cars, and homes of people suspected of drug use or sales.
On the (predictable) result of these incentives—plunder:
One highly publicized case involved a reclusive millionaire, Donald Scott, who was shot and killed when a multiagency task force raided his two-hundred-acre Malibu ranch purportedly in search of marijuana plants. They never found a single marijuana plant in the course of the search. A subsequent investigation revealed that the primary motivation for the raid was the possibility of forfeiting Scott’s property. If the forfeiture had been successful, it would have netted the law enforcement agencies about $5 million in assets. In another case, William Munnerlynn had his Learjet seized by the DEA after he inadvertently used it to transport a drug dealer. Though charges were dropped against him within seventy-two hours, the DEA refused to return his Learjet. Only after five years of litigation and tens of thousands of dollars in legal fees was he able to secure return of his jet. When the jet was returned, it had sustained $100,000 worth of damage.
