A grand jury in Kentucky declines to indict three police officers for the shooting death of Breonna Taylor in a drug raid gone wrong, leading to nationwide protests in the U.S.

A grand jury is a jury empowered by law to conduct legal proceedings, investigate potential criminal conduct, and determine whether criminal charges should be brought. A grand jury may subpoena physical evidence or a person to testify. A grand jury is separate from the courts, which do not preside over its functioning.

Kentucky, officially the Commonwealth of Kentucky, is a landlocked state in the Southeastern region of the United States. It borders Illinois, Indiana, and Ohio to the north, West Virginia to the northeast, Virginia to the east, Tennessee to the south, and Missouri to the west. Its northern border is defined by the Ohio River. Its capital is Frankfort and its most populous city is Louisville. As of 2024, the state's population was approximately 4.6 million.

Breonna Taylor was an African-American woman who was shot and killed while unarmed in her Louisville, Kentucky, home by three police officers who entered under the auspices of a "no-knock" search warrant. After Louisville Metro Police Department (LMPD) ex-detective Brett Hankison was acquitted of felony wanton endangerment of Taylor's neighbors at the state-level, Attorney General Merrick Garland announced the Department of Justice was charging Hankison with the unconstitutional use of excessive force that violated Taylor's civil rights. He was found guilty in November 2024. In July 2025, Hankison was sentenced to 33 months in prison, despite the Trump Department of Justice's request for no prison time, and three years of supervised release. Three other officers, who were not present at the shooting, were also federally charged with conspiracy in falsifying evidence to procure the search warrant, and then covering it up.

The Breonna Taylor protests were a series of police brutality protests surrounding the killing of Breonna Taylor. Taylor was a 26-year-old African-American woman who was fatally shot by plainclothes officers of the Louisville Metro Police Department on March 13, 2020. Police were initially given "no-knock" search warrant, but orders were changed to "knock and announce" before the raid. Taylor's boyfriend, Kenneth Walker, who was inside the apartment with her during the raid, said he thought the officers were intruders. He fired one shot, hitting officer Mattingly in the leg, and the officers fired 32 shots in return, killing Taylor.
