No convictions for St Louis officers who beat Black undercover colleague at protest

Officer Luther Hall, who was recording criminal activity during protests, required multiple surgeries after the attack

No convictions were returned for three white St Louis police officers accused of beating a Black undercover colleague so severely during a protest over another officer's acquittal that he had to undergo multiple surgeries.

A jury on Monday acquitted officer Steven Korte of charges of deprivation of rights under color of law and of lying to the FBI in connection to the attack on officer Luther Hall.
