Weather probably played a role. It's getting colder and black riots, like black crime in general, are usually a lot worse during hot weather. Also could be riot fatigue. They've been rioting almost continuously for 4 months straight, and Breonna was mentioned continually. Rioting and mass shooting season is kind of dying down in the US, but it will likely resume in force in late spring. You also didnt have footage that Jewish media outlets like CNN can play on an endless loop, fueling black rage as with Floyd.

Finally you have to understand this took place in Kentucky, so the local government and police arent as passive and cucked as in Minnesota or Wisconsin, and certainly Seattle and Portland and parts of cali where the riots have gone on indefinitely because they are backed by the local government and prosecutors.
