In the 60s the strategy was to make a circle around the white kids so they don't run when the cops come. Since then the police have decided to attack white kids regularly and the strategy has basically been anarchists Vs republicans (usually the police are not very liberal).
You are acting as if we have seen anything but anarchists, angry riots and gun toters Vs oppression, but we really haven't. No one has ever tried a "show of strength" or anything before. Not even occupy.
