Three days later, police arrested him on warrants related to roughly $1,500 in unpaid court debt dating back more than a decade. The consequences are more often cumulative and slow-moving, criminal justice reform advocacy groups like the Brennan Center for Justice and the Fines and Fees Justice Center note. These costs include fines as punishment for crime, mandatory court fees, probation and supervision fees, public defender reimbursement and a range of seemingly random administrative charges. A June report found that counties that impose higher criminal court fees also tended to have larger jail populations. If higher court fees ultimately lead to more detention, a policy meant to help fund the system may also increase one of its highest costs.
