How Kenosha County district attorney prosecutor Michael D. Graveley could decide not to prosecute Rusten Sheskey, the cop who shot Jacob Blake seven times in the back outside an apartment building last August, is beyond me. But at least this decision represents an opportunity. If BLM demonstrators can mobilize and start trashing Kenosha storefronts quickly enough, they might be able to depress the pro-Warnock and Osoff vote in Georgia. It might be too late, I realize, but they could at least give it the old college try.
