Looks like the controversy isn't over yet. In fact, the manhunt has just started. Leland Yee, California senator who made the 2005 Video Game Law, is demanding an explanation for ESRB's decision to give Take-Two Interactive's Manhunt 2 (for the Wii and PSP) an M rating, joining the protests raised by the Campaign for a Commercial-Free Childhood.

Yee is suspicious of the correspondence between ESRB and Rockstar, claiming that their rating system can't be trustworthy for as long as the decision to make it so was held behind closed doors.

Not only is Yee demanding the ESRB to reveal what had led them to change the rating, but also to reveal all the correspondence that was held between them and Rockstar. He stated in a press release that:

Parents can’t trust a rating system that doesn’t even disclose how they come to a particular rating. The ESRB and Rockstar should end this game of secrecy by immediately unveiling what content has been changed to grant the new rating and what correspondence occurred between the ESRB and Rockstar to come to this conclusion. Unfortunately, history shows that we must be quite skeptical of these two entities. [...] Clearly the ESRB has a conflict of interest in rating these games. It is time to bring transparency to this rating system and for the industry to be held accountable.
