I don't think any of this is purely inspired by George Floyd.
It has to be in part at least due to the covid lockdowns.
I am in my Alameda home right now (walking distance from Oakland) and it is eeerily quiet at night with all of the curfews and lockdowns. Usually when we erupt in violence, we erupt alone. It seems like all California, including San Diego is joining in. #blacklivesmatter protests are usually not that widespread.
