Hahaha, I guess Rockstar is starting to get the idea
I actually never really noticed the cop there, so thanks for pointing him out. Hopefully we'll see various different models and skins for cops. I mean, SA did
have a small variety, but only changed in different cities and depending on the type of cop, like a bike cop differed from the regular street walking/Police car cops. So maybe in GTA IV, we'll see tall cops, short cops, fat cops, thin cops, cops with hats, cops without hats, cops cops cops. Also hope the same applies to other sorts of groups.
