June 20, 2009 Mousavi called off Saturday's demonstration with good reason. Violence keeps away most who wish to protest and helps Khamanei. Mix a mass demonstration with rush-hour crowds. No one can tell who's who. The effect is amplified, by the normal crowds and traffic. Blend in; do not wear green, and obey the laws. Inevitably traffic will stop and news will be made. This makes it impossible for the Basij thugs to know who to attack. If they attack non-protesters, opinion will turn against them even more.
Tactics such as this—and there must be many others—make it possible to sustain a longer struggle and expose the regime's thuggery more clearly. Minimize casualties. Without weapons, more time and greater numbers are essential.
