I agree with you guys. I mean, Ice Cube really didn't fall that far, he didn't have the gangsta background. He was in NWA, but not as hardcore as Ice-T. He started off in Boyz n the Hood and Friday, and is now taking nut shots from toddlers in Disney movies.
On the other hand, Ice-T was a drug dealer, pimp, bank robber. The SVU character really isn't too big of a stretch (although the reality show is kinda lame). He may have changed the most from who he originally was, but he hasn't lost all street cred or anything, like Cube.
