An angry tweet by actor John Cusack against Fox News and its coverage of the lower Manhattan Islamic center controversey is being blown up by Fox in its own coverage of the incident, with claims it could incite violence and amounts to a threat.

A FoxNews.com web story on the incident stated:

Actor John Cusack went on a caustic Twitter rampage Sunday evening, attacking former House Majority Leader Dick Armey, former House Speaker Newt Gingrich and Fox News.

“I AM FOR A SATANIC DEATH CULT CENTER AT FOX NEWS HQ AND OUTSIDE THE OFFICES ORDICK ARMEYAND NEWT GINGRICH-and all the GOP WELFARE FREAKS,” Cusack tweeted.

Cusack has long been outspoken about politics. He supported Barack Obama in the 2008 presidential election and has contributed to The Huffington Post, but this is the first known time he has stooped to the level of making threats.

Threats? Really?

The story then went on to ask a psychiatrist about the alleged spark his comments could have to incite violence:

And while the U.S. Constitution protects Cusack's right to speak his mind, some critics say he should be more careful about what he says, since he has more than 200,000 Twitter followers.

“His provocative tweets could easily incite a rabid fan to commit violent acts against Fox News Headquarters and others he names,” said Dr. Carole Lieberman, a Beverly Hills-based psychiatrist and author of “Coping With Terrorism: Dreams Interrupted.”

“Fans could not only be influenced because of their devotion to Cusack, the man, but also because of their love for one of the characters he plays,” she told Fox411.

Cooper Lawrence, the author of “Cult of Celebrity” told Fox 411: “The fear isn't that a celebrity will influence someone to do something violent or out of character due to the sheer devotion to the celebrity, the fear is that someone who is already vulnerable, mentally disturbed, already considering something dangerous, may be encouraged to do so if it is advocated by their favorite star,”

It doesn't say anything about some of Fox's own caustic coverage and how that might incite viewers.
