I was thinking of Mahtma Gandi and organising a silent sitting protest. People could bring chairs or just sit for a few hours. Sit in silence with banners that put the message across. Silence is a very powerful tool. It would be hard for authorities to act harshly without looking bad. We could wear masks as a symbol of having been silenced. That would make it even harder to stop. Each mask could have 'silenced' on it. At the end the masks could be removed. Turn the tables on the authorities so to speak. I wouldn't know where to begin so would need a bit of help. What do you think.
