Use-of-force expert testifies that he did not perceive crowd as a threat Los Angeles Police Sergeant Jody Stiger, a use-of-force expert who analyzed the Floyd incident after his death, testified that the crowd gathered at the scene was not a threat. Stiger was asked by the prosecuting attorney to define a "hostile crowd" based on his own experience as a police officer. "I would define hostile crowd in the situations I've been in where the crowd or members of the crowd were threatening and/or throwing bottles and rocks at the police," he said. Stiger was asked if "name calling" and "foul language" directed at police by the bystanders factored into his analysis of the Floyd incident. He said it did not because "I did not perceive them as being a threat."
