When we we first spotted these people holding signs across the street from the Alexis Park, site of the CES high-end-audio exhibits, we thought they were merely calling attention to T.H.E. Expo at the Tuscany nearby, which is not sanctioned by the CES (the signs indicate directions for shuttle service and other exhibitor information for T.H.E. Expo). We later learned that they were part of a picketing campaign caused by controversy over shuttle buses from the Alexis Park to the Tuscany. Seems there was a near-scuffle in the morning. If this all sounds confusing, that's because it is.
