Berlin Answers Red Threat. West Berlin responds to the newest Communist threat by stockpiling food and staple supplies. Mindful of the blockade of 10 years ago. Meanwhile, 4,000 persons demonstrate in protest to a pro-communist rally. Heavy equipment moving stuff. Men standing in and shoveling grain (?). Truck pulls out. Sign says No Pictures Will Be Taken on the Autobahn, and then pan to truck traveling on the road (funny and ironic if that road IS the Autobahn). Police with helmets (gently) restrain crowd.
