Filmmaker Michael Moore called for a mass boycott of Georgia following the execution of convicted murderer Troy Davis.

Davis was convicted of killing an off-duty police officer named Mark MacPhail in 1989 and sat on Georgia’s Death Row since 1991. The execution outraged many over assertions that Davis may have been innocent after some witnesses recanted their testimony.

Davis was killed by lethal injection on Wednesday after the U.S. Supreme Court refused to order a stay of execution.

Moore has joined fellow celebrities Kim Kardashian, Mia Farrow and Alec Baldwin in condemning the execution and has now called for an economic boycott of Georgia.

Moore is even asking his publisher to pull his latest book, a memoir entitled Here Comes Trouble, from Georgia book stores.

He has explicitly referred to the racial dimension of the case – Davis was black, MacPhail was white.

“I encourage everyone I know to never travel to Georgia, never buy anything made in Georgia, to never do business in Georgia, said Moore on his Web site.

I will ask my publisher to pull my book from every Georgia bookstore. And if they won’t do that, I will donate every dime of every royalty my book makes in Georgia to help defeat the racists and killers who run that state. I ask all Americans with a conscience to shun anything and everything to do with the murderous state of Georgia.”
