Though it wasn't originally for that purpose, I can't think of a better way of organizing a protest... the anti-ISA people should keep it in mind. First of all, it's a little harder to arrest people as a group (Malaysia not having the freedom to congregate) if they're all 1) individually 2) doing nothing. Second, by the time the cops arrive, they've all blended into the public. All they need is a slogan, like "We stop so they will. ISA: it halts our way of life."
