The author of a new book reports on new tactics being used by some radical activists.
...peace activists have turned to radical tactics. They've moved beyond demonstrations and petitions into direct action, defying the government's laws and impeding its capacity for mass murder. Some of them have become domestic insurgents, helping soldiers to desert, destroying computer systems, trashing recruiting offices, burning military equipment and sabotaging defence contractors. As criminals for peace, they are defying the Patriot Act and working underground in secret cells to undermine the US military empire. They are convinced the only way to bring peace now is to bring the system down.
