One analyst said that the settlement was likely to mute his public pronouncements and lawsuits against the company. However, upon the game's 2008 release, Thompson called "Grand Theft Auto IV" "the gravest assault upon children in this country since polio," and asked Minnesota Governor Tim Pawlenty to "pursue and file criminal charges against retailers Target and Best Buy". He also sent a letter to Take-Two chairman Strauss Zelnick's attorney, addressed to Zelnick's mother, in which Thompson accused her son of "doing everything he possibly can to sell as many copies of GTA: IV to teen boys in the United States, a country in which your son claims you raised him to be a 'a Boy Scout'. ... More like the Hitler Youth, I would say." On May 1, 2008 Thompson appeared on the CNN Headline News program "Glenn Beck", asserting that the game's sexual content made its sale to minors illegal, and that he was working with law enforcement to have criminal prosecutions brought. Thompson also filed a complaint with the Chicago Transit Authority about poster ads for the game at Chicago, Illinois bus stops.
