The French Resistance and the Israeli Irgun were made up of cells. The use of cells is the next phase of any movement when progress has stopped, when a dead end has been reached, when death stares you in the face unless, when the only next step can only be revolutionary acts. Remember, America itself was started by a revolution. There were many cells indeed then. Take this idea one step further.
Cells can do anything.
Cells of lawyers can threaten class-action lawsuits against drug companies not dissimilarly to what is happening against tobacco. Cells can plaster cities to tell people to stop taking their drugs every other month. Cells can play havoc on the Internet, the most valuable tool ever put in the hands of activism. Yes, cells can do anything they want to. That is the beauty of the cell.
