Crump added: "If Brett Hankison's behavior was wanton endangerment to people in neighboring apartments, then it should have been wanton endangerment in Breonna Taylor's apartment too. In fact, it should have been ruled wanton murder!"

What to watch: Louisville Mayor Greg Fischer declared a state of emergency Tuesday and issued a 9 p.m. to 6:30 a.m. curfew "due to the potential for civil unrest" for the next three days. Most of the protests in Louisville since May have remained peaceful.

Portions of the city's downtown have been on virtual lockdown since late Monday . The Louisville Metro Police Department erected barricades, closing down traffic to vehicles.

The state's National Guard has also been activated, local officials said.

Protests are taking place in different parts of Louisville. Live video footage showed several protesters being detained as dozens marched down a prominent Louisville street.

Catch up quick: Taylor was alive for at least 20 minutes after police officers entered her home on March 13 and shot her during a drug investigation into her ex-boyfriend, who did not live there, the Louisville Courier Journal reports.

Officers used a battering ram to break down Taylor's door, despite her not being a main suspect, and shot her at least five times after her then-current boyfriend, Kenneth Walker, fired his gun at an officer in self-defense, per the Courier Journal.

Taylor did not receive medical attention after the shooting even though she showed signs of life, including coughing and labored breathing, according to Walker and police dispatch logs.

The Jefferson County coroner disputed that account to the New York Times, saying Taylor "had little to no chance of survival, and was likely to have died in 'less than a minute.'"
