Jack Thompson, the disbarred U.S. lawyer who unsuccessfully tried to limit the sale of Grand Theft Auto IV, has petitioned U.S. Secretary of Defense Robert Gates in an attempt to ban EA's Medal of Honor.

Thompson has objected to the Afghanistan-based FPS on grounds that U.S. Special Forces were involved in the developmental phase, providing a "powerful and useful training tool to rehearse killing our soldiers".

Much like New Zealand's Minister of Defence Wayne Mapp, Thompson is also arguing that allowing players to participate as Taliban forces is unacceptable.

Additionally, Thompson has claimed that Electronic Arts have not restricted pre-orders, and are accepting sales from minors, proof of which has yet to be supplied.

A partial transcript of Thompson's letter to Gates has been made available to various news agencies after first appearing on pcmag.com:

"With all respect for everything else on your plate, but as someone who has represented the surviving family members of such video game-caused massacres, I personally urge you, as Secretary of Defense, to do what is necessary, proper, and legal to stop the release of Medal of Honor on October 12 on the basis that it poses a demonstrable danger to our troops by providing a training tool for those who wish to kill them.

"I would also strongly suggest that the Defense Department find out who these Special Ops people are who have acted so foolishly in this regard.

"Finally, I believe the full weight of the federal government should come down upon Electronic Arts and the video game industry's Entertainment Software Association for their allowing, presently and fraudulently, despite promises to Congress, the widespread pre-sale of this adult game to minors throughout the country and around the world."

Thompson has also cryptically hinted that despite being disbarred, he may be planning another legal challenge in the coming days:

"I'm not representing anyone as a lawyer, as I am not a lawyer," Thompson said. "I am speaking on behalf of a number of people who believe that EA should not be selling such a game to minors, particularly one that allows one to play the role of the Taliban. Beyond that, I am not presently authorized to identify anyone. That may change in a day or two. I intend to stop the release of the game."

Thompson has a long history of litigious action against the gaming industry. In 2005 he accused Rockstar of producing a "murder simulator", and his filings to the Florida Bar have previously been described by the Florida Supreme Court as "repetitive, frivolous and insulting to the integrity of the court".

In 2008, Thompson was permanently disbarred by the Florida Supreme Court for inappropriate conduct, including making false statements to tribunals and disparaging and humiliating litigants.
