public OnPlayerRequestSpawn(playerid)
{
    if(PlayerInfo[playerid][pCopRights] != 1)
    {
        if(GetPlayerSkin(playerid) == [Your Id Skin Here])
        {
            SendClientMessage(playerid, SOME_COLOR, "You Need To Be A Cop bla bla..);
            return 0;
        }
    }
    return 1;
}

Ain't sure if it will work since it isn't tested, but i found a function like this in my script. And i can't compile that since i don't have PlayerInfo and such.
