They will not come on the property while your under the overhang. You should be at six stars and having a ball. Just keep 'bigbanging' them as they arrive or use the 'nuttertools' to open the gatling gun on them. Now you can see the vehicles coming to the house but the copter can't fire on you. Next the copter shows up, use the rocket launcher on it then hightail it off the roof and head to the overhang area in front of the house. When the cops show up snipe them to until there is a host of squad cars then 'bigfbang' them. One fun thing to try: Get on the roof of your mailibu house where the weapon is and start sniping people. I did learn some things even after playing this many times: you must save the game after finding hidden package or it goes back to the spot it was located and drives you nuts trying to figure out which ones you have and which ones you don't. No spending time looking for ammo or healh and armor: just type it in.
I have done the game all missions without cheats so this was different. Played the game using the heck out of cheats and it was fun fun fun. I think the answer may be I don't have all the packages yet, I'm shy 12 and am stealing the helicopter. I read in a post you can use the cannon and hit your targeting button to kill the cars but doesn't work for me. Only the rocker launcher and that is brutal trying to hit moving vehicles with that. I can't get the cannon of the Hunter to work.
