This is a point that I discuss in the GGLA know your rights training (which is called “Law Isn’t Real”) - the ability to actually file or pursue charges is irrelevant, the goal is control of space and the reestablishment of “order” (capitalist, white supremacist status quo ante)
It doesn’t matter that they can’t charge you or secure a conviction—that’s not the point! The point is that the charge, or its dismissal, or the lawsuit you win a year later, are all downstream from the reestablishment of control
