The Panama City News Herald reports that a man held a school board meeting in Florida at gunpoint and opened fire, after walking up to the podium and daubing a V symbol in a circle with spray paint on the wall

That symbol will be familiar to many comic book readers and film goers as the symbol used by the character V in the comic and movie V For Vendetta, a reworking of the famous Anarchy symbol, though the red paint is indicative of the film more than the comic.

Identified as Clay Duke, whose wife recently lost her school job, he was shot by former School Board member and district security chief Mike Jones, who was alerted to the incident, and the paper believes that Duke died as result. They also state that Duke's weapon was a cap gun.

The imagery of V For Vendetta, specifically that of Guy Fawkes has been popularised by a variety of protest groups since the movie's release, including the Anonymous group.

UPDATE: This is Clay Duke's Facebook page

And one of his Facebook photo albums under the title "What Must Be Done"

He also writes;

My Testament: Some people (the government sponsored media) will say I was evil, a monster (V)… no… I was just born poor in a country where the Wealthy manipulate, use, abuse, and economically enslave 95% of the population. Rich Republicans, Rich Democrats… same-same… rich… they take turns fleecing us… our few dollars… pyramiding the wealth for themselves. The 95%… the us, in US of A, are the neo slaves of the Global South. Our Masters, the Wealthy, do, as they like to us… "There's class warfare, all right, but its my class, the rich class that's making war and we're winning"
