After a Kentucky grand jury opted to indict only one of the three Louisville police officers in the raid that led to Breonna Taylor's death earlier this year, the city braced for protests.

Former Sgt. Brett Hankison was charged with three counts of wanton endangerment for firing rounds during the raid that went into neighboring apartments, but not in the death of Taylor.

The attorney for Taylor's family, Ben Crump, tweeted that the decision was "outrageous and offensive."

Taylor, a 26-year-old Black emergency medical worker, was shot five times by officers who entered her home using a no-knock warrant during a drug investigation March 13. State Attorney General Daniel Cameron clarified Wednesday that the officers did knock and announce themselves before entering. The use of no-knock warrants is now banned in the city. No drugs were found during the search.

Louisville Mayor Greg Fischer declared a state of emergency and announced a 72-hour curfew starting at 9 p.m.

The Louisville Metro Police Department announced it was putting barricades around the downtown perimeter where protests have been concentrated.

The Kentucky National Guard was also deployed in the city.
