December 2012, Rosh Chodesh, the Kotel. It’s the moment the policewoman pulls me aside because I am wearing my tallis. I say to her, “This must be incredibly hard for you to do.” (She looks back at me puzzled). Many hours later, after being interrogated and finally released from the Old City police station, concerned friends ask, “Were you afraid?” I was not. Since then, I’ve thought a good deal about what makes me afraid – and what does not.
