I disagree witht the premise implied in your post that social protest needs to be accmpanied by a specific set of policy prescriptions. I find this to be an oft-used tactic employed to discredit the act of social protest. It's not Kaep's responsibility to prescribe policy solutions; there's no 'How To' manual for social protest that everhone is obligated to agree to. His objective was to protest what he saw as inequities in how the US polices communities of color, and perhaps to raise consciousness about them, and perhaps to facilitate discussion about them. He purpose clearly is not to produce a White Paper on specific policy recommendations, and I fail to see why, if he does not inlcude this among his list of objectives, this somehow invalidates what he's doing.
As for the Bla bla bla, this is precisely what you, and so many others are doing: prescribing the pararmaters of social protest, from the comfort of belonging to the power group, to those who are outside the power group. You may not want to hear it, but you should at least be cognizant that this is what you're doing.
