Franklin Zimring quoted by NBC Bay Area, Oct. 27, 2017

“The threat that the police officer faces (when a suspect has an edged weapon) is not a threat to the police officer’s life,” said Zimring. … “The number of cases we found…of somebody with a visible weapon charging at a police officer actually killing the police officer in the United States was zero.” Zimring said. FBI data backs him up.
