The lesson is that we cannot go on relying on violence to defend us from violence. There is no such thing as a clean, sanitized military that can take over the job of protecting us. People have to protect themselves with the robustness of their institutions and integrity of their values. And there is no such thing as a “civil” violence that can shield us from criminal depredations.

The first lesson an awakened public should draw from the scenes at Berkeley and Davis is really that there’s no such thing as “appropriate” violence that can be contained in a corner and not spill out where we don’t want it—or more accurately, where we are forced to recognize what it really is.
