First get the people to feel comfortable turning in others for smoking. After a while, add a few things. Your neighbor doesn't recycle? Turn him/her in. Turn in your neighbor for receiving gun magazines. Turn in your neighbor for his/her opinion. What? your neighbor doesn't like some of the "modifications" to marriage that liberals like? Turn him/her in. What? Your neighbor doesn't like the fascist direction that the USA is going in? Turn him/her in!
We're already a nation of snitches. Just as these guys.
