Absolutely. They are just as guilty as the criminal.
Absolutely not. Only the criminal is at fault.

While they are not responsible for violence, they certainly cause unnecessary anger through manipulation of the truth.
"All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language...No man is an island, entire of itself...any man's death diminishes me, because I am involved in mankind; and therefore never send to know for whom the bell tolls; it tolls for thee." - John Donne
They can incite violence by actually telling their listeners to be violent.
Since that never happens, pundits cause as much violence as video games, comic books, pornography, movies, and the Beatles song "Helter Skelter": none.
I cannot think of a pundit that I think has "caused" violence right now. People are responsible for their own actions. In theory, sure, it could happen, but since the questions is do they, and not can they, I am going with no.
Pundits can help create an atmosphere of hatred that increases the outbreak of violence. However, at the end they aren't truly responsible for another's actions, especially from a legal perspective. I'd consider a few violent outbreaks from borderline crazies a fair trade for free speech any day of the week.
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
Cicero Marcus Tullius
Of course they do, else why do you have revolutions, attacks on political and governmental infrastructure. Someone has to stir up the pot with words to make people do those things.. they do not happen by themselves. It would be like saying Hitler is not at fault for Nazi Germany.
