The ex-Louisville police officer on trial for firing into Breonna Taylor’s apartment the night she was killed testified Thursday he had to react quickly after a fellow officer was shot in the leg during the drug raid. Brett Hankison said he saw a muzzle flash come from inside Taylor’s hallway after officers knocked down the door in the early hours of March 13, 2020, to execute a search warrant. “I had to react,” Hankison said on the witness stand in U.S. District Court Thursday.
