No tactic should be dismissed except on the basis of a Shari’ah prohibition or practical ineffectiveness. And effectiveness needs to be evaluated according to the context. It is unwise to restrict yourself to any particular approach.
Campaigns of civil disobedience, marches, demonstrations, sit-ins, etc, can be effective in two principal ways.
1. They are a means of publicly articulating demands. This, however, requires that those demands should be clear, specific, and achievable.
2. They can be an excellent method of system disruption. This, however, requires that they should be carefully targeted and held at key locations, instead of at any random or symbolic large gathering place or main street.
When marches and rallies simply fall into a daily or weekly routine, following a predictable pattern, they become little more than a crowd control training exercise for the police. They can allow them or end them at will.
Rather, ideally, the brave crowds of protesters could be sent to key facilities, companies, and points along the corporate supply chain, and so forth, to achieve practical impact instead of symbolic.
