A police officer was seen on camera firing what appeared to be pepper balls at a news crew during a live television broadcast of the second night of Louisville protests, prompting an apology from the Louisville Metro Police Department. A crew from WAVE-TV was downtown in the Kentucky city Friday night, covering demonstrations over the death of Breonna Taylor, a black woman killed by police in her own home in March. Police presence intensified around 9:45 p.m., as officers in riot gear stood shoulder-to-shoulder moving people down a key street near City Hall, the Courier Journal reported.
