That is a very selective reading of what happened here.
“The primary targets of the LMPD investigation were Jamarcus Glover and Adrian Walker, who were suspected of selling controlled substances from a drug house more than 10 miles away.[10][11] According to a Taylor family attorney, Glover had dated Taylor two years before and continued to have a “passive friendship”.[11] The search warrant included Taylor’s residence because it was suspected that Glover received packages containing drugs at Taylor’s apartment and because a car registered to Taylor had been seen parked on several occasions in front of Glover’s house.....
Kenneth Walker, who was licensed to carry a firearm, fired first, injuring a law enforcement officer, whereupon police returned fire into the apartment with more than 20 rounds. A wrongful death lawsuit filed against the police by the Taylor family’s attorney alleges that the officers, who entered Taylor’s home “without knocking and without announcing themselves as police officers”, opened fire “with a total disregard for the value of human life”, but the police account claims the officers did knock and announce themselves before forcing entry....
...Walker, a licensed firearm carrier, shot first, striking a police officer in the leg. In response, the officers opened fire with more than 20 rounds, hitting objects in the living room, dining room, kitchen, hallway, bathroom, and both bedrooms. Taylor was struck by five bullets[23][24] and pronounced dead at the scene.[25] No drugs were found in the apartment.[3] According to anonymous sources who spoke to WAVE3 News, one of the three officers allegedly fired blindly from the exterior of the residence, through a window with closed blinds and curtains; the sources said they do not believe Taylor was struck by any of the bullets fired by the officer who was outside.”
