From the movie V for Vendetta (2006)
"E: Can I ask about what you said on the tele?
E: Did you mean it?
V: Every word.
E: You really think that blowing up the parliament is going to make this country a better place.
V: There is no certainty only opportunity.
E: I think that you can be pretty certain that if anyone does show up Creedy will black bag every one of them.
V: People should not be afraid of their governments. Governments should be afraid of their people.
Evey: And you're going to make that happen by blowing up a building?
V: The building is a symbol, as is the act of destroying it. Symbols are given power by people. Alone, a symbol is meaningless, but with enough people, blowing up a building can change the world.
Evey: I wish I could believe that was possible."
