Local authorities work with Feds to do this, however. Civil asset forfeiture has been banned in various localities, but is still legal federally - so non-federal police arrange to have a Federal officer (DEA etc) on hand to take care of that part, and then a certain percentage is kept by the federal government and the rest given to the local authorities. So first it would need to be banned federally.
