So who are all these people protesting against?

I'm just curious, I don't really care. But to me it's kind of tantamount to protesting the virus and not being able to be in groups.

Who exactly are they protesting against?

Police are local. You elected them indirectly. You're responsible for them. St Paul has a black mayor. Is it his fault?

My biggest issue is making this a racial issue, because if you make it about shitty cops instead, it's a more solvable problem. Racism is some nebulous belief that you can only rant about but really do nothing tangible to solve.

Shitty cops affect everyone. It's why we have them wearing body cameras. And determining if something is racist or not is pretty difficult. But identifying horrible cops is easy.
