Lamont Washington, an investigator with the Louisville Metro Police Professional Standards Unit, said an officer did break the department's pursuit policy before a 2021 crash that killed 22-year-old Trevon Mitchell.
In the days following the march, protesters came to the woman's defense, saying she pointed her gun at a man driving a dark gray Ford Taurus in self-defense after he pulled out a gun and pointed it at demonstrators near his car.
Officers surrounded between 12 and 15 protesters near the intersection of South Sixth and West Chestnut streets.
Under the enforcement changes, pedestrians must stay out of the streets, and cars and pedestrians will not be allowed to block intersections for any length of time, LMPD said.
"For the most part, we have seen peaceful protests," Washington said in a news release late Saturday night. "However, we have experienced a lot of violence and chaos from those hiding behind the right to peacefully assemble and using it as a platform to tear up and destroy our city."
No charges will be filed in the case.
The Jefferson County Coroner's Office identified the victim as Joseph Koontz of Louisville.
Officers representing every division and the training office arrived during the morning show to present hundreds of ornaments.
