Guy Fawkes Day in a Guy Fawkes mask.

So it's Guy Fawkes Day today. What are you going to do in your Guy Fawkes mask?

Now -- more than four hundred years after the gruesome death of the man who plotted to blow up the Houses of Parliament with barrels of gunpowder -- members of the Occupy and Anonymous movements are hoping to provide their own reason to remember Guy Fawkes Night.

On Saturday, November 5, hundreds of protesters wearing the sinister black and white Guy Fawkes masks plan to march on Parliament in central London.

"It will be a night our government never forgets," Malcolm, a member of hacker group Anonymous, said with a smile. "Our government should be expecting us."...

So... people wearing the masks are threatening violence?

"They're very meaningful masks," said Alexandra Ricciardelli, who was rolling cigarettes on a table outside her tent in New York's Zuccotti Park two days before the anniversary of Fawkes' failed bombing attempt.

"It's not about bombing anything; it's about being anonymous – and peaceful."

To the 20-year-old from Keyport, New Jersey, the Fawkes mask "is about being against The Man – the power that keeps you down."....

Uh... that sounds really stupid. Maybe call up a professor and find out what he says:

"You can seize hold of it for any political purpose you want," [said Lewis Call, an assistant history professor at California Polytechnic in San Luis Obispo.] "That's the real power of it."...

"Gradually over the centuries, the meaning of Guy Fawkes has dramatically changed... The reputation of Guy Fawkes has been recuperated. Before he was originally seen as a terrorist trying to destroy England. Now he's seen more as a freedom fighter, a fighter for individual liberty against an oppressive regime. The political meaning of that figure has transformed."

Fawkes is Fawkes, but don't forget: A mask is a mask:

"People hide behind the masks, put the masks on and their identity is hidden. Therefore they can do a lot more than they would if they didn't have the masks," [said a 33-year-old man at Occupy London who didn't want to be named] after emerging sleepy-eyed from his tent.
