But back to the actual issue at hand, Foer cites civil asset forfeiture as the strongest evidence of need for federal intervention. Oh, if this were only the case.
As this Institute for Justice’s 2010 paper on the subject makes clear, the rise civil asset forfeiture is a direct result of federal involvement in local policing. In what are known as “equitable sharing” agreements, federal law enforcement split forfeiture proceeds with state and local law authorities, supposedly in relation to the amount of work the agencies put into the investigation. While the amount of money is discretionary by statute, all reports indicate that the default split is the maximum allowed: 80 percent to local agencies, 20 percent to the federal government.
