The mayor of Louisville, Kentucky has declared a state of emergency ahead of an expected decision on whether charges will be brought against the officers involved in the police killing of Breonna Taylor, an unarmed Black woman. Al Jazeera reports that the declaration will allow the mayor to implement curfews and other restrictions as needed but parts of downtown Louisville were already eerily quiet on Tuesday after the Louisville Metro Police Department closed down traffic to vehicles, barricaded streets, and prohibited street parking after having declared its own state of emergency in preparation for the expected announcement. The department also cancelled all off-day and holiday requests until further notice.
