Inevitable?

Your Crusading Blogger would like to join the chorus of voices that call for the end of looting and destructive demonstrations in Minneapolis and elsewhere, as a result of the death of George Floyd.  But in my heart, I am divided:  while lawful, peaceable action is always the way to go, what happens when one speaks truth to power -- at first whispering, then in a normal voice, and finally, shouting -- and power ignores you?  Indeed, deliberately and methodically (sometimes violently, or using economic means) silences you?
