Several weeks ago I purchased the graphic novel that the movie is based on. It was written during the 80's. It's a story about post-war England after the United States and Russia have supposedly cancelled each other out with nuclear conflagration which results in social upheaval. Then, along comes a fascist government to bring back order to the country. V is a former re-settlement camp prisoner who has now undertaken the task of getting revenge for his suffering as well as attempting to bring down the oppressive government...all while wearing a Guy Fawkes mask (if you don't know about Guy Fawkes or the Gunpowder Plot of 1605, see wikipedia).
One of the key quotes from the movie jumped out at me immediately when I first saw the trailer (and led me to get the novel)..."People should not be afraid of their governments. Governments should be afraid of their people." In essence, that's how a free society should be.
One of the first things you notice in the graphic novel is a street camera. It's plainly labeled, "For Your Protection." This government came about because the people allowed it to during a time of uncertainty. It happened quickly. However, we have to be cautious because the same thing is happening to us in a much slower fashion. In fact, I'd say that England was almost there...have you tried to purchase a firearm there recently? Have you tried walking down the street without being caught on a government surveillance camera? Neither can be done. They are only a few steps away from the world of V for Vendetta...but do they even know it? Would we know it if we were headed in that direction? Perhaps we already are.
The author begins his conclusion with this: "As to the violence that "V for Vendetta" portrays, wasn't it Thomas Jefferson that said, "The tree of liberty must be refreshed from time to time with the blood of patriots & tyrants. It is it's natural manure." Indeed."
