I was reading some of the forums with people complaining about the cops and I didn't understand what they had a problem with. I hadn't had any problems with the cops so I decided to test it out. I spent three hours just testing it out yesterday and I never came across the problems some people keep complaining about. These are some examples of what I was doing:
>killed two guys on top of Mount Chilliad, no one else around, no wanted level
>thought I'd got a wanted level when I got into a fight with four guys in the desert but there was no one around to call the cops and after I knocked them all out, no wanted level
>killed a guy behind a building at the docks with a silenced pistol, there were three guys just around the corner but no wanted level. I went back to the same area later and it was the same situation, three guys around the corner from a guy by himself, I shot him with shotgun, got a wanted level and the three guys were running off.
>managed to knock out five guys on the Vespucci boardwalk before I heard someone on the phone to the cops and I got a wanted level
>I shot a guy standing next a house near the lighthouse and got a wanted level. I though I had encountered what some people were talking about, until I turned and saw someone running away
So, to the people that are still complaining about the cops having eyes everywhere maybe just go actually test it out for yourselves. There was someone around when you killed someone on a mountain and got a wanted level.
