EXTRACT: Someone had an idea, and you read it in a book. An idea about starting from the beginning, erasing all the old mistakes, a fire burning with a purity that meant everyone could start again. While you painted the idea on walls and yelled it through a megaphone in Bourke St, someone somewhere else started to do it. Actually do it. And people died. And you quoted the book, that power comes from the barrel of a gun.
