Avoid patterns
Established patterns are the surveillance professional’s best friend. Most people do more or less the same thing every day. They get up, eat the same breakfast, get in the same car, and drive the same route to work. These patterns are the comforting trappings of daily life without which most of us would quickly cease functioning. But they also make it easy for anyone—even an amateur—to keep us under observation.
If you’re worried about watchers, don’t establish predictable patterns. Rent cars instead of owning. Avoid becoming a regular visitor to a single place. If you have to go to the same place every day, like work, take a different route every time you go. Randomly mix up modes of transportation—bike, bus, drive, or walk. Make life hard on your observers by never doing the same thing twice. The trick here is to make life as stressful for a surveillance team as possible. The more you make them work, the more exhausted they get, and the more mistakes they are likely to make.
