But law enforcement officials may have been working within the confines of the law when they took Clarke’s money. Under federal and state laws that allow what’s called “civil forfeiture,” law enforcement officers can seize and keep someone’s property without proving the person was guilty of a crime. They just need probable cause to believe the assets are being used as part of criminal activity, typically drug trafficking. Police can then absorb the value of this property — be it cash, cars, guns, or something else — as profit: either through state programs, or under a federal program known as Equitable Sharing that lets local and state police get up to 80 percent of the value of what they seize as money for their departments.
