Each year, Child Protective Services (CPS) investigates over one million families. Every CPS investigation includes a thorough, room by-room search of the family home, designed to uncover evidence of maltreatment. Most seek evidence of poverty-related allegations of neglect; few ever substantiate the allegations. Despite what in many cities amounts to dozens of daily home invasions by government agents, the most remarkable feature of CPS home searches is how uncommon it has been for courts to clarify their legal parameters. More surprising than the relative dearth of case law and scholarship on the subject is the conclusion some courts have reached that these investigations are outside the familiar rules regulating law enforcement searches of homes.
