4. Suddenly leaving a car and walking hurriedly down a one-way street in the direction in which vehicle traffic is prohibited. 5. Entering a dark street in a residential area at night, making a sharp U-turn, cutting into a side alley, and extinguishing the car’s lights. 6. Driving to a rural area, taking a long walk in a field, then having another car meet them. 7. Waiting until the last minute, then making a sharp left turn in front of oncoming traffic. 8. Stopping at every filling station on the highway, walking around the car, always looking, then going on. _On foot_: 1. Leaving subways, buses, and trains at the last minute, even holding the door open and jumping off. 2. Entering hotels, bus terminals, and department stores where there are many exits. 3. Stooping over in the aisles, then suddenly rising and looking around to see if anybody is searching for them. 4. Doubling back after rounding a corner. 5. Putting a coin in a pay telephone booth, dialing a number, then rushing to the adjoining booth to see if anybody is trying to listen. 6. Leaving a taxicab, but instructing the driver to go around the block and pick them up again. 7. Using store windows as mirrors to see behind them. 8. Walking slowly to a corner, then starting to run down an alleyway. Always there is the fear of being followed. One Party couple registered at a motel, then the husband parked the car several miles away. He walked back and climbed through a side window. Maybe in this way he could conceal his night’s lodging! A woman in a Midwestern city kept riding streetcars, buses, and taxis for thirty hours, stopping at no time except for meals. In communist language she was “_dry-cleaning_”; that is, making certain that she was not being followed. The pressure becomes terrific. As long as a comrade feels he is “dirty” (that is, he suspects the “enemy,” meaning the FBI, is near), he must keep up his “dry-cleaning.” He can make his “meet” or enter a hide-out only when he’s certain he is “clean.” Two dry-cleaning techniques are of special interest. One is the _switch-point_ operation: The communist leader is driven to a certain location in a car (called a “drop car”). There he alights and enters another car (called a “pickup car”). Before entering the second car, however, he will walk across a parking lot, over a bridge, or through a department store—the object being to lose any pursuer. In the double switch, the pickup car drops the Party leader at a second switch, where he will be picked up by a third vehicle and then taken to his destination.
