That complaint accused police of knocking at the apartment door, then immediately breaking it down and “spraying” with 9 mm and .40 mm submachine guns and .40 mm Glock pistols. The suit also alleged that the marshal or marshals involved with the task force tampered with evidence by handcuffing Robinson after he was dead and throwing a flash grenade into the apartment to cover up evidence.

The mother’s suit is against various local governments and 11 officers. It remains the subject of grappling in U.S. District Court in Atlanta, where attorneys for the defendants have been arguing against it and trying to get it thrown out.
