Just for my own understanding, because i'm pretty torn on this, is there any point short of murder where the riot/protest crosses from the morally neutral "language of the unheard" territory and into "ok this is wrong and needs to be stopped"?
Nothing until your storm troopers stop killing us.
My storm troopers?
Yours as in all of y'alls. White men are the only people who have the power to change this. Once the power structure in this country gets either sick of this or scared of the response will there be any change to policing. I won't even think about asking for a change in systematic racism, that is too big of an ask at this point.
I'm not saying that you as an individual has any blame here, but you certainly have the ability to be part of a coalition to change what's happening in this country. We don't hire cops, we don't draft and oversee policy. We don't run the unions. We don't run the districts attorney offices. We've been told that taking a knee at sporting events isn't an acceptable form of protest. We've been told that social disobedience isn't an acceptable form of protest.
We have no way to fix this and have been told so. These cops are doing the bidding for white people, enforcing laws made by white people, and answering to white people. They're your cops, not mine.
Put it like this, someone is breaking into your house, do you have to think twice as to whether or not you need to call the cops? I do.
