Easy Walk Free Achievement
Go to the northern most road in Bohan, the small island where you get a safehouse after your first one gets burned down. There is a point where the elevated train tracks come down and go into a tunnel. Stand beside that place and shoot people and cops until you get 4 stars. Then jump or drive over the edge and land on the train tracks below and head into the tunnel. Just keep going until you are out of the search radius and you lose you wanted level. But to do this you will need to have unlocked the island of Algonquin (the middle one) or else you'll get 6 stars for crossing under the river.

Eventually you'll cross the river and end up on the locked island of Algonquin and receive 6 stars. Stay in the tunnel for 5 minutes and you'll get the achievement.

P.S. If you're in a car, if you stop shooting, it reloads by itself.

Fly to Happiness Island and once you get over the Statue of Liberty, jump out of the helicopter at the statue's feet. You should land on the topmost part of the statue, which is basically a square platform with a door in the center of each side.
Run around the platform until you see a door with a plaque on either side of it that reads, "No Hidden Content Here." The door doesn't open. You have to walk THROUGH the door. Inside, you'll find an empty room with a tall ladder. Climb it, and when you reach the top, look up; there is a surprise waiting for you.
Go to an ATM and cause a traffic jam in the area. Wait for someone to take money out of the ATM, then kill them. Make sure you have blocked any nearby roads so an ambulance can't get to the victim. Take the money they dropped, then run a short distance away and go back. The money should respawn on the ground. You can repeat this as many times as you want. You can also kill more people and take their money from the ATM to increase the amount that respawns.
