`Many people on the rundown northwest Atlanta street where Kathryn Johnston lived fortify their windows with metal bars and arm themselves for protection. Johnston, 92, was no exception. She was waiting with her gun on Tuesday night when a group of plainclothes officers with a warrant knocked down her door in a search for drugs, police said. She opened fire, wounding three officers, before being shot to death, police said.
Assistant Police Chief Alan Dreher called the killing “tragic and unfortunate” but said the officers were justified in returning fire.’
