Jack Thompson whatever, he's old news trying to keep himself in the headlines.
I'm going to go get GTA4 when it releases, and I'm thinking about buying a PS3 with it. I'm going to brutally murder every single beautifully pixelated biped in that game. In between killing sprees I might play with one of my two adopted kittens or I might cuddle with my fiancee (who I plan to marry in a year). You will notice the lack of "slaughtering police officers" in my daily plans.
As gamers, we all know that this guy is full of it. Violent games will continue to be produced, the world will continue to spin, and we will continue to get outright pissed at idiots like Jack Thompson. Just try to ignore him and enjoy the games which make his blood boil. :-D That's my satisfaction, right there.
