An old (2016) but still important study on Chicago and civil forfeiture, who it benefits (cops and prosecutors) and who it harms (including people who committed no crimes):
Since 2009, the year CPD began keeping electronic records of its forfeiture accounts, the department has brought in nearly $72 million in cash and assets through civil forfeiture, keeping nearly $47 million for itself and sending on almost $18 million to the Cook County state’s attorney’s office and almost $7.2 million to the Illinois State Police, according to our analysis of CPD records.
