Missouri Attorney General Chris Koster is pushing for changes to court rules in an effort to halt what he calls abusive debt-collection actions.

Koster will be in St. Louis Thursday to spell out details of his plan. The Democrat says research shows that abusive debt-collection practices disproportionately target minorities.

The treatment of black and other minority residents in the St. Louis region has come under scrutiny in the 16 months since the fatal shooting of 18-year-old Michael Brown, who was black and unarmed. The white Ferguson police officer who shot Brown, Darren Wilson, was not charged, but the shooting led to an examination of the way courts, police and others interact with minority residents in the St. Louis region.
