Most artists have embarrassing, half-baked ideas in their youth that they can point to from a mature distance with laughter. Maybe the creative team here will be able to do that some day. A disjointed collection of sketches related to the Black Lives Matter movement, “Arrest Me” is a simple-minded jumble of of-the-moment themes, and its characters reproduce some of the very stereotypes at the heart of the dehumanization of black people. Writer K.D. Howells notes that “theater is a time capsule of social history.” But shows need to say something coherently to stand the test of time.
